SYSTEM privilege escalation via unquoted service path
Published Jan 27, 2026 · Updated Jan 27, 2026
Unquoted service path in Segurazo SAntivirus IC 10.0.21.61 allows local users to execute code with SYSTEM privileges. The SAntivirusIC Windows service registers an unquoted executable path under C:\Program Files (x86), so Windows can select an attacker-planted executable at an earlier space-delimited path component. A low-privileged local user must place a malicious file in a searched parent path and wait for the LocalSystem service to start, after which the payload runs as SYSTEM.
