The version of Firefox ESR installed on the remote Windows host is prior to 115.12. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-26 advisory.

  - Memory corruption in the networking stack could have led to a potentially exploitable crash.
    (CVE-2024-5702)

  - If a garbage collection was triggered at the right time, a use-after-free could have occurred during     object transplant. (CVE-2024-5688)

  - By monitoring the time certain operations take, an attacker could have guessed which external protocol     handlers were functional on a user's system. (CVE-2024-5690)

  - By tricking the browser with a <code>X-Frame-Options</code> header, a sandboxed iframe could have     presented a button that, if clicked by a user, would bypass restrictions to open a new window.
    (CVE-2024-5691)

  - On Windows 10, when using the 'Save As' functionality, an attacker could have tricked the browser into     saving the file with a disallowed extension such as <code>.url</code> by including an invalid character in     the extension. Note: This issue only affected Windows operating systems. Other operating systems are     unaffected. (CVE-2024-5692)

  - Offscreen Canvas did not properly track cross-origin tainting, which could be used to access image data     from another site in violation of same-origin policy. (CVE-2024-5693)

  - By manipulating the text in an <code><input></code> tag, an attacker could have caused corrupt     memory leading to a potentially exploitable crash. (CVE-2024-5696)

  - Memory safety bugs present in Firefox 126, Firefox ESR 115.11, and Thunderbird 115.11. 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-2024-5700)

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