Local privilege escalation via unsigned binary loading
Published Apr 15, 2020 · Updated Aug 4, 2024
Elevation of privilege in Microsoft RMS Sharing for Mac allows local users with low privileges to execute unsigned binaries. The application's privileged binary-loading path accepts unsigned code without enforcing the expected signature validation before execution. Microsoft has not published the affected file or function; exploitation requires local low-privilege access and grants code execution with elevated rights.
