"The version of Firefox installed on the remote Windows host is prior to 101.0. It is, therefore, affected by multiple
vulnerabilities as referenced in the mfsa2022-20 advisory.

  - A malicious website could have learned the size of a cross-origin resource that supported Range requests.
    (CVE-2022-31736)

  - A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a
    potentially exploitable crash. (CVE-2022-31737)

  - When exiting fullscreen mode, an iframe could have confused the browser about the current state of
    fullscreen, resulting in potential user confusion or spoofing attacks. (CVE-2022-31738)

  - When downloading files on Windows, the % character was not escaped, which could have lead to a download
    incorrectly being saved to attacker-influenced paths that used variables such as %HOMEPATH% or %APPDATA%.
    This bug only affects Firefox for Windows. Other operating systems are unaffected. (CVE-2022-31739)

  - On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation
    problem, and a potentially exploitable crash. (CVE-2022-31740)

  - A crafted CMS message could have been processed incorrectly, leading to an invalid memory read, and
    potentially further memory corruption. (CVE-2022-31741)

  - An attacker could have exploited a timing attack by sending a large number of allowCredential entries and
    detecting the difference between invalid key handles and cross-origin key handles.  This could have led to
    cross-origin account linking in violation of WebAuthn goals. (CVE-2022-31742)

  - Firefox's HTML parser did not correctly interpret HTML comment tags, resulting in an incongruity with
    other browsers. This could have been used to escape HTML comments on pages that put user-controlled data
    in them. (CVE-2022-31743)

  - An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and
    in doing so bypass a page's Content Security Policy. (CVE-2022-31744)

  - If array shift operations are not used, the Garbage Collector may have become confused about valid
    objects. (CVE-2022-31745)

  - An attacker could have caused an uninitialized variable on the stack to be mistakenly freed, causing a
    potentially exploitable crash. (CVE-2022-1919)

  - Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory
    safety bugs present in Firefox 100 and Firefox ESR 91.9. 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-2022-31747)

  - Mozilla developers Gabriele Svelto, Timothy Nikkel, Randell Jesup, Jon Coppeard, and the Mozilla Fuzzing
    Team reported memory safety bugs present in Firefox 100. 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-2022-31748)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
