Technical ContextAI · show details
This vulnerability is classified as SQL Injection (CWE-89), which allows attackers to execute arbitrary SQL commands against the database. MapServer is a system for developing web-based GIS applications. Prior to 8.4.1, the XML Filter Query directive PropertyName is vulnerably to Boolean-based SQL injection. It seems like expression checking is bypassed by introducing double quote characters in the PropertyName. Allowing to manipulate backend database queries. This vulnerability is fixed in 8.4.1. Affected products include: Osgeo Mapserver. Version information: Prior to 8.4.1.

Executive ViewAI
Organizations using MapServer face significant risk from CVE-2025-59431, a SQL injection vulnerability rated CVSS 8.9. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.
