Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The CMService.exe service runs with SYSTEM privileges and contains an unquoted service path. This allows a local attacker with write privileges to the filesystem to insert a malicious executable in the path, leading to privilege escalation.
