Suricata versions prior to 7.0.17 and 8.0.6 on Windows are vulnerable due to improper handling of unquoted service ImagePath, allowing local low-privileged attackers to execute arbitrary programs with LocalSystem privileges. This vulnerability poses a significant risk of local privilege escalation, making it critical for organizations using Suricata on Windows to prioritize upgrading to the patched versions. System administrators and security teams should take immediate action to mitigate this risk.

Original NVD Description

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.
