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.","published":"2026-09-18T21:17:00.787","modified":"2026-09-18T21:17:00.787","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/OISF/suricata/commit/0dad38fff024b4fec9bc8144d8b94dbca39aac2e","label":"OISF/suricata@0dad38f"},"references":[{"type":"WEB","url":"https://github.com/OISF/suricata/commit/0dad38fff024b4fec9bc8144d8b94dbca39aac2e"},{"type":"WEB","url":"https://github.com/OISF/suricata/commit/2b924d47cc51d0b7760cda3519f2c04a2f65ea38"},{"type":"WEB","url":"https://github.com/OISF/suricata/commit/ac1b3cc1ef3af65ce92da28261d445167eb8234d"},{"type":"WEB","url":"https://github.com/OISF/suricata/pull/15676"},{"type":"WEB","url":"https://github.com/OISF/suricata/releases/tag/suricata-7.0.17"},{"type":"WEB","url":"https://github.com/OISF/suricata/releases/tag/suricata-8.0.6"},{"type":"WEB","url":"https://github.com/OISF/suricata/security/advisories/GHSA-jh8w-wf3f-58jp"},{"type":"WEB","url":"https://redmine.openinfosecfoundation.org/issues/8600"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T21:17:00.787"}}
