SYSTEM code execution via unquoted service path
Published Feb 12, 2020 · Updated Aug 5, 2024
Unquoted search path in HP System Event Utility before 1.4.33 allows local users to execute arbitrary code as SYSTEM. The HPMSGSVC.exe service starts an attacker-supplied C:\Program.exe because its executable path is not safely quoted. Exploitation requires local file-write access to the root of C: and elevates an administrator-level attacker to SYSTEM.
