The version of Firefox ESR installed on the remote Windows host is prior to 140.4. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-83 advisory.

  - A malicious page could have used the type attribute of an OBJECT tag to override the default browser     behavior when encountering a web resource served without a content-type. This could have contributed to an     XSS on a site that unsafely serves files without a content-type header. (CVE-2025-11712)

  - Use-after-free in MediaTrackGraphImpl::GetInstance() (CVE-2025-11708)

  - A compromised web process was able to trigger out of bounds reads and writes in a more privileged process     using manipulated WebGL textures. (CVE-2025-11709)

  - A compromised web process using malicious IPC messages could have caused the privileged browser process to     reveal blocks of its memory to the compromised process. (CVE-2025-11710)

  - There was a way to change the value of JavaScript Object properties that were supposed to be non-     writeable. (CVE-2025-11711)
