Local privilege escalation via improper update validation
Published Apr 15, 2020 · Updated Aug 4, 2024
Improper update validation in Microsoft AutoUpdate for Mac before 4.22 allows local users to execute code with elevated privileges. The update-download and execution path accepts an insecure connection and executes an update without adequate validation; Microsoft has not disclosed the exact failed check. Exploitation requires local low-privileged access and control over delivered update content, with execution occurring in the updater's elevated context.
