Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

"The remote Windows host is missing security update 4038779
or cumulative update 4038777. It is, therefore, affected by
multiple vulnerabilities :

  - A race condition that could lead to a remote code
    execution vulnerability exists in NetBT Session Services
    when NetBT fails to maintain certain sequencing
    requirements. (CVE-2017-0161)

  - A spoofing vulnerability exists in Microsoft's
    implementation of the Bluetooth stack. An attacker who
    successfully exploited this vulnerability could perform
    a man-in-the-middle attack and force a user's computer
    to unknowingly route traffic through the attacker's
    computer. The attacker can then monitor and read the
    traffic before sending it on to the intended recipient.
    (CVE-2017-8628)

  - An elevation of privilege vulnerability exists in
    Windows when the Windows kernel-mode driver fails to
    properly handle objects in memory. An attacker who
    successfully exploited this vulnerability could run
    arbitrary code in kernel mode. An attacker could then
    install programs; view, change, or delete data; or
    create new accounts with full user rights. To exploit
    this vulnerability, an attacker would first have to log
    on to the system. An attacker could then run a specially
    crafted application that could exploit the vulnerability
    and take control of an affected system. The update
    addresses this vulnerability by correcting how the
    Windows kernel-mode driver handles objects in memory.
    (CVE-2017-8675)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. (CVE-2017-8676)

  - A remote code execution vulnerability exists when the
    Windows font library improperly handles specially
    crafted embedded fonts. An attacker who successfully
    exploited this vulnerability could take control of the
    affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights. (CVE-2017-8682)

  - An information disclosure vulnerability exists when the
    Microsoft Windows Graphics Component improperly handles
    objects in memory. An attacker who successfully
    exploited the vulnerability could obtain information to
    further compromise the users system. (CVE-2017-8683)

  - A information disclosure vulnerability exists when the
    Windows GDI+ component improperly discloses kernel
    memory addresses. An attacker who successfully exploited
    the vulnerability could obtain information to further
    compromise the users system.
    (CVE-2017-8677, CVE-2017-8680, CVE-2017-8681,
    CVE-2017-8684, CVE-2017-8685)

  - An Information disclosure vulnerability exists in
    Windows kernel that could allow an attacker to retrieve
    information that could lead to a Kernel Address Space
    Layout Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the memory address of a kernel object. (CVE-2017-8687)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface+ (GDI+)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. (CVE-2017-8688)

  - An information disclosure vulnerability exists when
    Windows Uniscribe improperly discloses the contents of
    its memory. An attacker who successfully exploited the
    vulnerability could obtain information to further
    compromise the users system. There are multiple ways an
    attacker could exploit the vulnerability, such as by
    convincing a user to open a specially crafted document
    or by convincing a user to visit an untrusted webpage.
    The update addresses the vulnerability by correcting how
    Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could take control of the affected system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2017-8696)

  - A remote code execution vulnerability exists when
    Windows Shell does not properly validate file copy
    destinations. An attacker who successfully exploited the
    vulnerability could run arbitrary code in the context of
    the current user.
    (CVE-2017-8699)

  - An information disclosure vulnerability exists when
    Windows Hyper-V on a host operating system fails to
    properly validate input from an authenticated user on a
    guest operating system. (CVE-2017-8707)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address, allowing an attacker to retrieve information
    that could lead to a Kernel Address Space Layout
    Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the base address of the kernel driver from a compromised
    process. (CVE-2017-8708)

  - An information disclosure vulnerability exists in the
    Windows System Information Console when it improperly
    parses XML input containing a reference to an external
    entity. An attacker who successfully exploited this
    vulnerability could read arbitrary files via an XML
    external entity (XXE) declaration. To exploit the
    vulnerability, an attacker could create a file
    containing specially crafted XML content and convince an
    authenticated user to open the file. The update
    addresses the vulnerability by modifying the way that
    the Windows System Information Console parses XML input.
    (CVE-2017-8710)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could obtain information to further compromise the users
    system. (CVE-2017-8678, CVE-2017-8679, CVE-2017-8709,
    CVE-2017-8719)

  - An elevation of privilege vulnerability exists in
    Windows when the Win32k component fails to properly
    handle objects in memory. An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts
    with full user rights. (CVE-2017-8720)

  - A spoofing vulnerability exists when Internet Explorer
    improperly handles specific HTML content. An attacker
    who successfully exploited this vulnerability could
    trick a user into believing that the user was visiting a
    legitimate website. The specially crafted website could
    either spoof content or serve as a pivot to chain an
    attack with other vulnerabilities in web services. To
    exploit the vulnerability, the user must either browse
    to a malicious website or be redirected to it. In an
    email attack scenario, an attacker could send an email
    message in an attempt to convince the user to click a
    link to the malicious website. (CVE-2017-8733)

  - An information disclosure vulnerability exists in
    Microsoft browsers due to improper parent domain
    verification in certain functionality. An attacker who
    successfully exploited the vulnerability could obtain
    specific information that is used in the parent domain.
    (CVE-2017-8736)

  - A remote code execution vulnerability exists in the way
    that Microsoft browser JavaScript engines render content
    when handling objects in memory. The vulnerability could
    corrupt memory in such a way that an attacker could
    execute arbitrary code in the context of the current
    user. (CVE-2017-8741, CVE-2017-8748)

  - A remote code execution vulnerability exists when
    Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user. (CVE-2017-8747,
    CVE-2017-8749)

  - A remote code execution vulnerability exists when
    Microsoft browsers improperly access objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user. (CVE-2017-8750)

  - A remote code execution vulnerability exists when
    Microsoft .NET Framework processes untrusted input. An
    attacker who successfully exploited this vulnerability
    in software using the .NET framework could take control
    of an affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights. (CVE-2017-8759)

  - An information disclosure vulnerability exists in
    Microsoft browsers in the scripting engines due to
    improper handling of objects in memory. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose files on a user's computer. (CVE-2017-8529)");

"The remote Windows host is missing security update 4038781.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists when
    Microsoft Windows PDF Library improperly handles objects
    in memory. The vulnerability could corrupt memory in a
    way that enables an attacker to execute arbitrary code
    in the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user. If the current
    user is logged on with administrative user rights, an
    attacker could take control of an affected system. An
    attacker could then install programs; view, change, or
    delete data; or create new accounts with full user
    rights.  (CVE-2017-8728, CVE-2017-8737)

  - An information disclosure vulnerability exists when
    Windows Hyper-V on a host operating system fails to
    properly validate input from an authenticated user on a
    guest operating system.  (CVE-2017-8706, CVE-2017-8707,
    CVE-2017-8713)

  - An information disclosure vulnerability exists when the
    Microsoft Windows Graphics Component improperly handles
    objects in memory. An attacker who successfully
    exploited the vulnerability could obtain information to
    further compromise the users system.  (CVE-2017-8683)

  - An Information disclosure vulnerability exists in
    Windows kernel that could allow an attacker to retrieve
    information that could lead to a Kernel Address Space
    Layout Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the memory address of a kernel object.  (CVE-2017-8687)

  - A remote code execution vulnerability exists when
    Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that enables an attacker to execute arbitrary code in
    the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2017-8734)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability.  (CVE-2017-8676)

  - A remote code execution vulnerability exists in the way
    that Microsoft browser JavaScript engines render content
    when handling objects in memory. The vulnerability could
    corrupt memory in such a way that an attacker could
    execute arbitrary code in the context of the current
    user. In a web-based attack scenario, an attacker could
    host a specially crafted website that is designed to
    exploit the vulnerability through Microsoft browsers and
    then convince a user to view the website. An attacker
    could also embed an ActiveX control marked &quot;safe
    for initialization&quot; in an application or Microsoft
    Office document that hosts the related rendering engine.
    The attacker could also take advantage of compromised
    websites, and websites that accept or host user-provided
    content or advertisements. These websites could contain
    specially crafted content that could exploit the
    vulnerability. An attacker who successfully exploited
    the vulnerability could gain the same user rights as the
    current user.  (CVE-2017-8741, CVE-2017-8748)

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Microsoft Edge. The vulnerability could corrupt memory
    in such a way that an attacker could execute arbitrary
    code in the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2017-8738,
    CVE-2017-8753, CVE-2017-8756)

  - A race condition that could lead to a remote code
    execution vulnerability exists in NetBT Session Services
    when NetBT fails to maintain certain sequencing
    requirements.  (CVE-2017-0161)

  - A remote code execution vulnerability exists in the way
    Microsoft Edge handles objects in memory. The
    vulnerability could corrupt memory in such a way that an
    attacker could execute arbitrary code in the context of
    the current user. An attacker who successfully exploited
    the vulnerability could gain the same user rights as the
    current user.  (CVE-2017-8757)

  - A remote code execution vulnerability exists when
    Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user.  (CVE-2017-8747,
    CVE-2017-8749)

  - An elevation of privilege vulnerability exists in
    Windows when the Win32k component fails to properly
    handle objects in memory. An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts
    with full user rights.  (CVE-2017-8720)

  - An information disclosure vulnerability exists when
    Windows Uniscribe improperly discloses the contents of
    its memory. An attacker who successfully exploited the
    vulnerability could obtain information to further
    compromise the users system. There are multiple ways an
    attacker could exploit the vulnerability, such as by
    convincing a user to open a specially crafted document
    or by convincing a user to visit an untrusted webpage.
    The update addresses the vulnerability by correcting how
    Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - An information disclosure vulnerability exists when
    Microsoft Edge improperly handles clipboard events. For
    an attack to be successful, an attacker must persuade a
    user to visit a malicious website and leave it open
    during clipboard activities. The update addresses the
    vulnerability by changing how Microsoft Edge handles
    clipboard events in the browser. (CVE-2017-8643)

  - A spoofing vulnerability exists in Microsoft's
    implementation of the Bluetooth stack. An attacker who
    successfully exploited this vulnerability could perform
    a man-in-the-middle attack and force a user's computer
    to unknowingly route traffic through the attacker's
    computer. The attacker can then monitor and read the
    traffic before sending it on to the intended recipient.
    (CVE-2017-8628)

  - An information disclosure vulnerability exists in
    Microsoft browsers due to improper parent domain
    verification in certain functionality. An attacker who
    successfully exploited the vulnerability could obtain
    specific information that is used in the parent domain.
    (CVE-2017-8736)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2017-8678, CVE-2017-8679, CVE-2017-8709,
    CVE-2017-8719)

  - A vulnerability exists when Microsoft Edge improperly
    accesses objects in memory. The vulnerability could
    corrupt memory in such a way that an attacker could
    execute arbitrary code in the context of the current
    user.  (CVE-2017-11766)

  - A security feature bypass exists in Microsoft Edge when
    the Edge Content Security Policy (CSP) fails to properly
    validate certain specially crafted documents. An
    attacker who exploited the bypass could trick a user
    into loading a page containing malicious content.
    (CVE-2017-8723, CVE-2017-8754)

  - A remote code execution vulnerability exists when
    Microsoft .NET Framework processes untrusted input. An
    attacker who successfully exploited this vulnerability
    in software using the .NET framework could take control
    of an affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights. Users whose accounts are
    configured to have fewer user rights on the system could
    be less impacted than users who operate with
    administrative user rights.  (CVE-2017-8759)

  - A information disclosure vulnerability exists when the
    Windows GDI+ component improperly discloses kernel
    memory addresses. An attacker who successfully exploited
    the vulnerability could obtain information to further
    compromise the users system.  (CVE-2017-8677,
    CVE-2017-8681)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability.  (CVE-2017-8688)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could take control of the affected system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2017-8692)

  - An elevation of privilege vulnerability exists in
    Windows when the Windows kernel-mode driver fails to
    properly handle objects in memory. An attacker who
    successfully exploited this vulnerability could run
    arbitrary code in kernel mode. An attacker could then
    install programs; view, change, or delete data; or
    create new accounts with full user rights.
    (CVE-2017-8675)

  - A spoofing vulnerability exists when Microsoft Edge does
    not properly parse HTTP content. An attacker who
    successfully exploited this vulnerability could trick a
    user by redirecting the user to a specially crafted
    website. The specially crafted website could either
    spoof content or serve as a pivot to chain an attack
    with other vulnerabilities in web services.
    (CVE-2017-8735)

  - A spoofing vulnerability exists when Internet Explorer
    improperly handles specific HTML content. An attacker
    who successfully exploited this vulnerability could
    trick a user into believing that the user was visiting a
    legitimate website. The specially crafted website could
    either spoof content or serve as a pivot to chain an
    attack with other vulnerabilities in web services.
    (CVE-2017-8733)

  - A remote code execution vulnerability exists when
    Microsoft browsers improperly access objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user.  (CVE-2017-8750)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address, allowing an attacker to retrieve information
    that could lead to a Kernel Address Space Layout
    Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the base address of the kernel driver from a compromised
    process.  (CVE-2017-8708)

  - A remote code execution vulnerability exists when the
    Windows font library improperly handles specially
    crafted embedded fonts. An attacker who successfully
    exploited this vulnerability could take control of the
    affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights.  (CVE-2017-8682)

  - An elevation of privilege vulnerability exists in
    Windows Error Reporting (WER) when WER handles and
    executes files. The vulnerability could allow elevation
    of privilege if an attacker can successfully exploit it.
    An attacker who successfully exploited the vulnerability
    could gain greater access to sensitive information and
    system functionality.  (CVE-2017-8702)

  - A remote code execution vulnerability exists when
    Windows Shell does not properly validate file copy
    destinations. An attacker who successfully exploited the
    vulnerability could run arbitrary code in the context of
    the current user. If the current user is logged on with
    administrative user rights, an attacker could take
    control of the affected system. An attacker could then
    install programs; view, change, or delete data; or
    create new accounts with full user rights. Users whose
    accounts are configured to have fewer user rights on the
    system could be less impacted than users who operate
    with administrative user rights.  (CVE-2017-8699)
    
  - An information disclosure vulnerability exists in
    Microsoft browsers in the scripting engines due to
    improper handling of objects in memory. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose files on a user's computer. (CVE-2017-8529)");

  - A race condition that could lead to a remote code
    execution vulnerability exists in NetBT Session Services
    when NetBT fails to maintain certain sequencing
    requirements. (CVE-2017-0161)

  - A vulnerability exists when Microsoft Edge improperly
    accesses objects in memory. The vulnerability could
    corrupt memory in such a way that an attacker could
    execute arbitrary code in the context of the current
    user. (CVE-2017-11766)

  - A spoofing vulnerability exists in Microsoft's
    implementation of the Bluetooth stack. An attacker who
    successfully exploited this vulnerability could perform
    a man-in-the-middle attack and force a user's computer

    descriptionThe Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in Microsoft Office software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. The security update addresses the vulnerability by correcting how Microsoft Office handles files in memory. (CVE-2017-8630, CVE-2017-8744) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. There are multiple ways an attacker could exploit this vulnerability. In a web- based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker

  • NASL familyWindows : Microsoft Bulletins
    NASL idSMB_NT_MS17_SEP_OFFICE_VIEWERS.NASL
    descriptionThe Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in Microsoft Office software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. The security update addresses the vulnerability by correcting how Microsoft Office handles files in memory. (CVE-2017-8631) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. There are multiple ways an attacker could exploit this vulnerability. In a web- based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker

  • NASL familyWindows : Microsoft Bulletins
    NASL idSMB_NT_MS17_SEP_WIN2008.NASL
    descriptionThe remote Windows host is missing multiple security updates released on 2017/09/12. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. To exploit the vulnerability, an attacker on a guest operating system could run a specially crafted application that could cause the Hyper-V host operating system to disclose memory information. An attacker who successfully exploited the vulnerability could gain access to information on the Hyper-V host operating system. The security update addresses the vulnerability by correcting how Hyper-V validates guest operating system user input. (CVE-2017-8707) - An information disclosure vulnerability exists in the Windows System Information Console when it improperly parses XML input containing a reference to an external entity. An attacker who successfully exploited this vulnerability could read arbitrary files via an XML external entity (XXE) declaration. To exploit the vulnerability, an attacker could create a file containing specially crafted XML content and convince an authenticated user to open the file. The update addresses the vulnerability by modifying the way that the Windows System Information Console parses XML input. (CVE-2017-8710) - An Information disclosure vulnerability exists in Windows kernel that could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (KASLR) bypass. An attacker who successfully exploited this vulnerability could retrieve the memory address of a kernel object. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability by correcting how the Windows kernel handles memory addresses. (CVE-2017-8687) - An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system. The update addresses the vulnerability by correcting the way in which the Windows Graphics Component handles objects in memory. (CVE-2017-8683) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. There are multiple ways an attacker could exploit this vulnerability. In a web- based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker
