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 4471321. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. An attacker who successfully exploited this 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. 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-2018-8540) - A Denial Of Service vulnerability exists when Connected User Experiences and Telemetry Service fails to validate certain function values. An attacker who successfully exploited this vulnerability could deny dependent security feature functionality. (CVE-2018-8612) - An information disclosure vulnerability exists when the Windows GDI component 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 security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8595, CVE-2018-8596) - A remote code execution vulnerability exists in Windows where Microsoft text-to-speech fails to properly handle objects in the 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-2018-8634) - 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. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8631) - 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-2018-8639) - An elevation of privilege vulnerability exists when the Diagnostics Hub Standard Collector Service improperly impersonates certain file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. An attacker with unprivileged access to a vulnerable system could exploit this vulnerability. The security update addresses the vulnerability by ensuring the Diagnostics Hub Standard Collector Service properly impersonates file operations. (CVE-2018-8599) - 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-2018-8477) - An information disclosure vulnerability exists when Remote Procedure Call runtime improperly initializes objects in memory. (CVE-2018-8514) - A remote code execution vulnerability exists in the way that the Chakra 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-2018-8617, CVE-2018-8618, CVE-2018-8624, CVE-2018-8629) - An elevation of privilege vulnerability exists when the Windows kernel 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-2018-8611) - A remote code execution vulnerability exists in the way that the VBScript engine 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-2018-8625) - A remote code execution vulnerability exists when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user). (CVE-2018-8619) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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-2018-8643) - A denial of service vulnerability exists when .NET Framework improperly handles special web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an .NET Framework web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework application. The update addresses the vulnerability by correcting how the .NET Framework web application handles web requests. (CVE-2018-8517) - 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-2018-8641) - A remote code execution vulnerability exists in Windows Domain Name System (DNS) servers when they fail to properly handle requests. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the Local System Account. Windows servers that are configured as DNS servers are at risk from this vulnerability. (CVE-2018-8626)

"The remote Windows host is missing security update 4471324.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists when the
    Microsoft .NET Framework fails to validate input
    properly. An attacker who successfully exploited this
    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. 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-2018-8540)

  - A Denial Of Service vulnerability exists when Connected
    User Experiences and Telemetry Service fails to validate
    certain function values. An attacker who successfully
    exploited this vulnerability could deny dependent
    security feature functionality.  (CVE-2018-8612)

  - An information disclosure vulnerability exists when the
    Windows GDI component 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 security update addresses the vulnerability by
    correcting how the Windows GDI component handles objects
    in memory. (CVE-2018-8595, CVE-2018-8596)

  - A remote code execution vulnerability exists in Windows
    where Microsoft text-to-speech fails to properly handle
    objects in the 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-2018-8634)

  - 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-2018-8637)

  - A denial of service vulnerability exists when .NET
    Framework improperly handles special web requests. An
    attacker who successfully exploited this vulnerability
    could cause a denial of service against an .NET
    Framework web application. The vulnerability can be
    exploited remotely, without authentication. A remote
    unauthenticated attacker could exploit this
    vulnerability by issuing specially crafted requests to
    the .NET Framework application. The update addresses the
    vulnerability by correcting how the .NET Framework web
    application handles web requests. (CVE-2018-8517)

  - An elevation of privilege vulnerability exists when the
    Diagnostics Hub Standard Collector Service improperly
    impersonates certain file operations. An attacker who
    successfully exploited this vulnerability could gain
    elevated privileges. An attacker with unprivileged
    access to a vulnerable system could exploit this
    vulnerability. The security update addresses the
    vulnerability by ensuring the Diagnostics Hub Standard
    Collector Service properly impersonates file operations.
    (CVE-2018-8599)

  - 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-2018-8477)

  - An information disclosure vulnerability exists when
    Remote Procedure Call runtime improperly initializes
    objects in memory.  (CVE-2018-8514)

  - An elevation of privilege vulnerability exists when the
    Windows kernel 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-2018-8611)

  - A remote code execution vulnerability exists in Windows
    Domain Name System (DNS) servers when they fail to
    properly handle requests. An attacker who successfully
    exploited the vulnerability could run arbitrary code in
    the context of the Local System Account. Windows servers
    that are configured as DNS servers are at risk from this
    vulnerability.  (CVE-2018-8626)

  - 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-2018-8641)

  - 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-2018-8639)");

    descriptionThe remote Windows host is missing security update 4471327. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. An attacker who successfully exploited this 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. 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-2018-8540) - A remote code execution vulnerability exists in the way that the Chakra 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-2018-8583, CVE-2018-8617, CVE-2018-8618, CVE-2018-8624, CVE-2018-8629) - A Denial Of Service vulnerability exists when Connected User Experiences and Telemetry Service fails to validate certain function values. An attacker who successfully exploited this vulnerability could deny dependent security feature functionality. (CVE-2018-8612) - An information disclosure vulnerability exists when the Windows GDI component 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 security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8595, CVE-2018-8596) - A remote code execution vulnerability exists in Windows where Microsoft text-to-speech fails to properly handle objects in the 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-2018-8634) - 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. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8631) - 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-2018-8639) - An elevation of privilege vulnerability exists when the Diagnostics Hub Standard Collector Service improperly impersonates certain file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. An attacker with unprivileged access to a vulnerable system could exploit this vulnerability. The security update addresses the vulnerability by ensuring the Diagnostics Hub Standard Collector Service properly impersonates file operations. (CVE-2018-8599) - 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-2018-8477) - An information disclosure vulnerability exists when Remote Procedure Call runtime improperly initializes objects in memory. (CVE-2018-8514) - An elevation of privilege vulnerability exists when the Windows kernel 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-2018-8611) - A remote code execution vulnerability exists in the way that the VBScript engine 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-2018-8625) - A remote code execution vulnerability exists when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user). (CVE-2018-8619) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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-2018-8643) - A denial of service vulnerability exists when .NET Framework improperly handles special web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an .NET Framework web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework application. The update addresses the vulnerability by correcting how the .NET Framework web application handles web requests. (CVE-2018-8517) - 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-2018-8641)
