Detailsinfo

A vulnerability, which was classified as very critical, was found in OISF Suricata up to 7.0.16/8.0.5. This affects some unknown functionality of the file src/win32-service.c of the component Windows Service Installation. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-57223 since 06/24/2026. The exploitability is told to be easy. An attack has to be approached locally.
