SYSTEM code execution via MSI repair race
Published Feb 27, 2024 · Updated Aug 15, 2024
Privilege escalation in Thales SafeNet Authentication Client before 10.8 R10 allows local users to execute code as SYSTEM on Windows. The MSI repair workflow stages a wac*.tmp executable in the caller's writable temporary directory and later runs it with elevated privileges, allowing a race to replace that file with attacker-controlled code. Local access and successful timing of the repair race are required; exploitation yields full SYSTEM-level control.
