Technical details

A SQL injection vulnerability exists in SemCms versions up to and including 5.0. The flaw is located in the 'pid' parameter within the SEMCMS_Quanxian.php file, which fails to properly neutralize special elements before using them in a SQL command (CWE-89). An attacker with low-privileged network access can send specially crafted requests to execute arbitrary SQL queries. Successful exploitation allows the attacker to read sensitive data from the database, modify records, or potentially gain administrative (DBA) permissions depending on the database configuration. A proof-of-concept has been identified in public disclosures.
