The version of Firefox installed on the remote Windows host is prior to 130.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-39 advisory.

  - A difference in the handling of StructFields and ArrayTypes in WASM could be used to trigger an     exploitable type confusion vulnerability. (CVE-2024-8385)

  - A potentially exploitable type confusion could be triggered when looking up a property name on an object     being used as the <code>with</code> environment. (CVE-2024-8381)

  - Multiple prompts and panels from both Firefox and the Android OS could be used to obscure the notification     announcing the transition to fullscreen mode after the fix for CVE-2023-6870 in Firefox 121. This could     lead to spoofing the browser UI if the sudden appearance of the prompt distracted the user from noticing     the visual transition happening behind the prompt. These notifications now use the Android Toast feature.
    This bug only affects Firefox on Android. Other operating systems are unaffected. (CVE-2024-8388)

  - Internal browser event interfaces were exposed to web content when privileged EventHandler listener     callbacks ran for those events. Web content that tried to use those interfaces would not be able to use     them with elevated privileges, but their presence would indicate certain browser features had been used,     such as when a user opened the Dev Tools console. (CVE-2024-8382)

  - Firefox normally asks for confirmation before asking the operating system to find an application to handle     a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes     news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an     unscrupulous program that the user downloaded could register itself as a handler. The website that served     the application download could then launch that application at will. (CVE-2024-8383)

  - The JavaScript garbage collector could mis-color cross-compartment objects if OOM conditions were detected     at the right point between two passes. This could have led to memory corruption. (CVE-2024-8384)

  - If a site had been granted the permission to open popup windows, it could cause Select elements to appear     on top of another site to perform a spoofing attack. (CVE-2024-8386)

  - Memory safety bugs present in Firefox 129, Firefox ESR 128.1, and Thunderbird 128.1. 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-2024-8387)

  - Memory safety bugs present in Firefox 129. 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-2024-8389)

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