The version of firefox installed on the remote host is prior to 102.13.0-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-001 advisory.
An attacker could have triggered a use-after-free condition when creating a WebRTC connection over HTTPS.
This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13. (CVE-2023-37201)
Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free. This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13. (CVE-2023-37202)
A website could have obscured the fullscreen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13.
(CVE-2023-37207)
When opening Diagcab files, Firefox did not warn the user that these files may contain malicious code.
This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13. (CVE-2023-37208)
Memory safety bugs present in Firefox 114, Firefox ESR 102.12, and Thunderbird 102.12. 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. This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13. (CVE-2023-37211)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
