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.

    descriptionThe remote Windows host is missing security update 4034658. It is, therefore, affected by multiple vulnerabilities : - A denial of service vulnerability exists when Microsoft Windows improperly handles NetBIOS packets. An attacker who successfully exploited this vulnerability could cause a target computer to become completely unresponsive. A remote unauthenticated attacker could exploit this vulnerability by sending a series of TCP packets to a target system, resulting in a permanent denial of service condition. The update addresses the vulnerability by correcting how the Windows network stack handles NetBIOS traffic. (CVE-2017-0174) - A buffer overflow vulnerability exists in the Microsoft JET Database Engine that could allow remote code execution on an affected system. An attacker who successfully exploited this vulnerability could take complete 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-2017-0250) - 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. (CVE-2017-0293) - An elevation of privilege vulnerability exists in Microsoft Edge that could allow an attacker to escape from the AppContainer sandbox in the browser. An attacker who successfully exploited this vulnerability could gain elevated privileges and break out of the Edge AppContainer sandbox.The vulnerability by itself does not allow arbitrary code to run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (for example a remote code execution vulnerability and another elevation of privilege vulnerability) to take advantage of the elevated privileges when running.The security update addresses the vulnerability by modifying how Microsoft Edge handles sandboxing. (CVE-2017-8503) - A remote code execution vulnerability exists in Windows Input Method Editor (IME) when IME improperly handles parameters in a method of a DCOM class. The DCOM server is a Windows component installed regardless of which languages/IMEs are enabled. An attacker can instantiate the DCOM class and exploit the system even if IME is not enabled. (CVE-2017-8591) - 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.

    successfully exploited this vulnerability could take
    complete control of an affected system. An attacker
    could then install programs; view, change, or delete

    (CVE-2017-0250)

  - 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. (CVE-2017-0293)

  - An elevation of privilege vulnerability exists in
    Microsoft Edge that could allow an attacker to escape
    from the AppContainer sandbox in the browser. An
    attacker who successfully exploited this vulnerability
    could gain elevated privileges and break out of the Edge
    AppContainer sandbox.The vulnerability by itself does
    not allow arbitrary code to run. However, this
    vulnerability could be used in conjunction with one or
    more vulnerabilities (for example a remote code

    privilege vulnerability) to take advantage of the
    elevated privileges when running.The security update
    addresses the vulnerability by modifying how Microsoft
    Edge handles sandboxing. (CVE-2017-8503)

  - A remote code execution vulnerability exists in Windows
    Input Method Editor (IME) when IME improperly handles
    parameters in a method of a DCOM class. The DCOM server
    is a Windows component installed regardless of which
    languages/IMEs are enabled. An attacker can instantiate
    the DCOM class and exploit the system even if IME is not
    enabled. (CVE-2017-8591)

  - 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;

  - A remote code execution vulnerability exists when
    Windows Search 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

    the vulnerability through an SMB connection and then
    take control of a target computer.The security update
    addresses the vulnerability by correcting how Windows
    Search handles objects in memory. (CVE-2017-8620)

  - A denial of service vulnerability exists when Microsoft
    Hyper-V Network Switch on a host server fails to
    properly validate input from a privileged user on a
    guest operating system. An attacker who successfully
    exploited the vulnerability could cause the host server
    to crash. (CVE-2017-8623)

  - An elevation of privilege vulnerability exists when the
    Windows Common Log File System (CLFS) driver improperly
    handles objects in memory.(CVE-2017-8624)

  - A security feature bypass vulnerability exists when
    Internet Explorer fails to validate User Mode Code
    Integrity (UMCI) policies. The vulnerability could allow
    an attacker to bypass Device Guard UCMI policies.To
    exploit the vulnerability, a user could either visit a
    malicious website or an attacker with access to the
    system could run a specially crafted application. An
    attacker could then leverage the vulnerability to run
    unsigned malicious code as though it were signed by a
    trusted source.The update addresses the vulnerability by
    correcting how Internet Explorer validates UMCI
    policies. (CVE-2017-8625)

  - This security update resolves a vulnerability in Windows
    Error Reporting (WER). The vulnerability could allow
    elevation of privilege if successfully exploited by an
    attacker. An attacker who successfully exploited this
    vulnerability could gain greater access to sensitive
    information and system functionality. This update
    corrects the way the WER handles and executes files.
    (CVE-2017-8633)

  - A remote code execution vulnerability exists in the way
    JavaScript engines render when handling objects in
    memory in Microsoft browsers. 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-2017-8635)

  - 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

  - 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-2017-8639)

  - 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-2017-8640)

  - A remote code execution vulnerability exists in the way
    JavaScript engines render when handling objects in
    memory in Microsoft browsers. 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-2017-8641)

  - An information disclosure vulnerability exists when
    Microsoft Edge improperly handles objects in memory. An

  - A remote code execution vulnerability exists in the way
    Microsoft browsers handle objects in memory while
    rendering content. 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. If
    the current user is logged on with administrative user
    rights, an attacker who successfully exploited the
    vulnerability 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-2017-8669)
