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 version of Firefox installed on the remote Windows host is prior to 76.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-16 advisory. - A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This resulted in a potentially exploitable crash. (CVE-2020-12387) - The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox escape.Note: this issue only affects Firefox on Windows operating systems. (CVE-2020-12388, CVE-2020-12389) - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash.

  - A race condition when running shutdown code for Web

    resulted in a potentially exploitable crash.

  - The Firefox content processes did not sufficiently

    escape.Note: this issue only affects Firefox on
    Windows operating systems. (CVE-2020-12388,
    CVE-2020-12389)

  - A buffer overflow could occur when parsing and
    validating SCTP chunks in WebRTC. This could have led to
    memory corruption and a potentially exploitable crash.
    (CVE-2020-6831)

  - Incorrect origin serialization of URLs with IPv6

    (CVE-2020-12390)

  - Documents formed using data: URLs in an
    object element failed to inherit the CSP of
    the creating context. This allowed the execution of
    scripts that should have been blocked, albeit with a
    unique opaque origin. (CVE-2020-12391)

  - The 'Copy as cURL' feature of Devtools' network tab did
    not properly escape the HTTP POST data of a request,
    which can be controlled by the website. If a user used
    the 'Copy as cURL' feature and pasted the command into a
    terminal, it could have resulted in the disclosure of
    local files. (CVE-2020-12392)

  - The 'Copy as cURL' feature of Devtools' network tab did
    not properly escape the HTTP method of a request, which
    can be controlled by the website. If a user used the
    'Copy as cURL' feature and pasted the command into a
    terminal, it could have resulted in command injection
    and arbitrary command execution.Note: this issue
    only affects Firefox on Windows operating systems.
    (CVE-2020-12393)

  - A logic flaw in our location bar implementation could
    have allowed a local attacker to spoof the current
    location by selecting a different origin and removing
    focus from the input element. (CVE-2020-12394)

  - Mozilla developers and community members Alexandru
    Michis, Jason Kratzer, philipp, Ted Campbell, Bas
    Schouten, Andr Bargull, and Karl Tomlinson reported
    memory safety bugs present in Firefox 75 and Firefox ESR
    68.7. Some of these bugs showed evidence of memory
    corruption and we presume that with enough effort some
    of these could have been exploited to run arbitrary
    code. (CVE-2020-12395)

  - Mozilla developers and community members Frederik Braun,
    Andrew McCreight, C.M.Chang, and Dan Minor reported
    memory safety bugs present in Firefox 75. Some of these

    can be controlled by the website. If a user used the

    Michis, Jason Kratzer, philipp, Ted Campbell, Bas
    Schouten, Andr Bargull, and Karl Tomlinson reported
    memory safety bugs present in Firefox 75 and Firefox ESR
