The version of Firefox ESR installed on the remote Windows host is prior to 102.15. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-35 advisory.

  - When receiving rendering data over IPC <code>mStream</code> could have been destroyed when initialized,     which could have led to a use-after-free causing a potentially exploitable crash. (CVE-2023-4573)

  - When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks     could have been created at a time and eventually all simultaneously destroyed as soon as one of the     callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash.
    (CVE-2023-4574)

  - When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could     have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks     finished. This could have led to a use-after-free causing a potentially exploitable crash. (CVE-2023-4575)

  - On Windows, an integer overflow could occur in <code>RecordedSourceSurfaceCreation</code> which resulted     in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. This     bug only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2023-4576)

  - Excel <code>.xll</code> add-in files did not have a blocklist entry in Firefox's executable blocklist     which allowed them to be downloaded without any warning of their potential harm. (CVE-2023-4581)

  - Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and     Thunderbird 115.1. 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-2023-4584)

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