Provenance

Reported as

unquoted Windows search path vulnerability in Quest KACE Agent for Windows versions 12.0.38 and 13.1.23.0

Mechanism

The KSchedulerSvc.exe and AMPTools.exe components have an unquoted service path. A local attacker can place a malicious executable in a parent directory that is parsed before the intended executable, leading to code execution with NT AUTHORITY\SYSTEM privileges when the service starts.

Detection & mitigation

Monitor for unexpected child processes of services with unquoted service paths, especially those spawning from suspicious directories like C:\Program.exe or C:\Program Files\Quest\KACE\AMPTools.exe. Mitigate by ensuring all service paths are quoted and applying vendor patches.
