CVE-2026-57223: CWE-428: Unquoted Search Path or Element in OISF suricata
CVE-2026-57223 is a local privilege escalation vulnerability in Suricata affecting Windows installations prior to versions 7.0.17 and 8.0.6. The issue arises from unquoted service ImagePath parameters during service installation, which can allow a low-privileged local attacker to execute arbitrary code as LocalSystem if the installation path contains spaces and an earlier path component is writable. This vulnerability has a high severity rating and is fixed in Suricata versions 7.0.17 and 8.0.6.
AI Analysis
Technical Summary
Suricata versions before 7.0.17 and 8.0.6 on Windows are vulnerable to a local privilege escalation due to unquoted search path elements in the service ImagePath used in CreateServiceA calls. When Suricata is installed under a directory path containing spaces, and an attacker has write permissions on an earlier path component, Windows may execute an attacker-controlled executable with LocalSystem privileges. This vulnerability is identified as CWE-428 (Unquoted Search Path or Element) and has been addressed in the specified fixed versions.
Potential Impact
A local low-privileged attacker can exploit this vulnerability to execute arbitrary code with LocalSystem privileges on affected Suricata Windows installations. This elevates the attacker's privileges significantly, potentially compromising the entire system's security.
Mitigation Recommendations
Upgrade Suricata to version 7.0.17 or later, or 8.0.6 or later, where this vulnerability has been fixed. No other mitigation is required once the software is updated.
