AI-suggested

Until an official fix is available, restrict access to the /api/stl/actions/dynamic endpoint to trusted users only, and monitor for suspicious activity. Avoid exposing the vulnerable endpoint publicly and consider implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting this endpoint.

Description

SSCMS v7.4.0 contains a SQL injection vulnerability in the stl:sqlContent tag where the queryString attribute is passed directly to database execution without parameterization or sanitization. Attackers can craft encrypted payloads submitted to the /api/stl/actions/dynamic endpoint to execute arbitrary SQL statements, leading to unauthorized database access, data disclosure, authentication bypass, data modification, or complete database compromise.
