Code execution via user-writable DLL search path
Published Nov 21, 2023 · Updated Aug 2, 2024
Uncontrolled DLL search in Duet for Windows 2.5.9.1 allows local users to execute arbitrary code when a user starts the application. The application loads libusk.dll from the user-writable C:\Users\user\AppData\Local\Microsoft\WindowsApps\ directory without restricting the search to a trusted location. An attacker must place the DLL locally and induce user interaction; successful loading runs attacker code and enables persistence.
