CVE-2023-47113

Privilege escalation via writable DLL search path

Published Nov 8, 2023 · Updated Sep 6, 2024

DLL search-order hijacking in BleachBit for Windows 4.4.2 and earlier allows local users to execute arbitrary code. bleachbit.exe and bleachbit_console.exe load a planted DLL from the user-writable c:\DLLs directory during startup. A low-privileged user must place the DLL and wait for another user to launch BleachBit; default UAC elevation runs the payload elevated.
