Endpoint Vulnerability

Further Privilege escalation through Mozilla Updater

Description

Security researcher Ash reported an issue with the Mozilla Updater on Windows 7 and later versions of Windows. On vulnerable platforms, the Mozilla Updater can be made to load a specific malicious DLL file from the local system. This DLL file can run in a privileged context through the Mozilla Maintenance Service's privileges, allowing for local privilege escalation. The DLL file can also run in an unprivileged context if the Mozilla Updater is run directly by a user in the same directory as the file. Local file system access is necessary in order for this issue to be exploitable.
