Doc Text:
A flaw was found in Suricata, a network Intrusion Detection System (IDS), Intrusion Prevention System (IPS), and Network Security Monitoring engine. On Windows, the service installation logic can pass an unquoted service ImagePath. This allows a local low-privileged attacker to execute arbitrary code with LocalSystem privileges if Suricata is installed in a path containing spaces and an earlier path component is writable. This can lead to local privilege escalation.

Description OSIDB Bzimport 2026-09-22 16:39:45 UTC 
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, the Windows service installation and parameter-update logic in src/win32-service.c can pass an unquoted service ImagePath to CreateServiceA. When Suricata is installed below a path containing spaces and an earlier path component is writable by a local low-privileged attacker, Windows can execute an attacker-controlled program as LocalSystem, resulting in local privilege escalation. This issue is fixed in versions 8.0.6 and 7.0.17.
