Technical description

baserCMS before 5.3.0 contains a SQL injection vulnerability in BcDatabaseService.php that allows authenticated administrators to inject attacker-controlled table names and configuration values directly into SQL statements across sequence update, CSV export, and table management operations. Attackers can chain a backup restore code injection flaw, where PHP code outside class definitions in schema files executes unconditionally upon loading, to plant malicious table names and trigger error-based SQL injection that retrieves database version, schema contents, and arbitrary data from the PostgreSQL backend.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
