SYSTEM code execution via unquoted service path
Published Jan 13, 2026 · Updated Jan 13, 2026
Unquoted service path handling in Cooler Master MasterPlus+ 1.8.5 allows local users to execute code with SYSTEM privileges. MPService registers its auto-start binary path without quotation marks, causing Windows to search earlier path segments for an executable. A local user who can write C:\Program.exe gains the service account's privileges when the service starts or the system reboots.
