Untrusted search path vulnerability in the installer in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, and Thunderbird ESR 10.x before 10.0.7 on Windows allows local users to gain privileges via a Trojan horse executable file in a root directory.

Security readout for executives and security teams

This is an old Mozilla installer weakness on Windows. A local user could potentially use the installer's unsafe file-search behavior to gain higher privileges. Business risk is mainly in unmanaged legacy endpoints or stored old installer packages, not current supported Mozilla deployments. Exposure is most likely where Windows systems still run or reinstall Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, or Thunderbird ESR 10.x before 10.0.7. Treat this as a legacy hygiene and privilege-escalation issue. It should be prioritized if affected Mozilla versions or old installers remain in Windows environments, especially on shared or multi-user systems. Mitigation focus: Upgrade Firefox to 15.0 or later, or ESR 10.0.7 or later.; Upgrade Thunderbird to 15.0 or later, or ESR 10.0.7 or later.; Remove obsolete Mozilla installers from shared folders, deployment caches, and endpoint software repositories..
