The version of Firefox ESR installed on the remote Windows host is prior to 115.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-02 advisory.

  • An out of bounds write in ANGLE could have allowed an attacker to corrupt memory leading to a potentially exploitable crash. (CVE-2024-0741)

  • It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by the user due to an incorrect timestamp used to prevent input after page load. (CVE-2024-0742)

  • A Linux user opening the print preview dialog could have caused the browser to crash. (CVE-2024-0746)

  • When a parent page loaded a child in an iframe with <code>unsafe-inline</code>, the parent Content Security Policy could have overridden the child Content Security Policy. (CVE-2024-0747)

  • A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user into granting permissions. (CVE-2024-0750)

  • A malicious devtools extension could have been used to escalate privileges. (CVE-2024-0751)

  • In specific HSTS configurations an attacker could have bypassed HSTS on a subdomain. (CVE-2024-0753)

  • Memory safety bugs present in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6. 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-2024-0755)

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