Title
SSCMS v7.4.0 SQL Injection via stl:sqlContent queryString
Summary
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.

Title
SSCMS v7.4.0 Reflected Cross-Site Scripting via STL Processing
Summary
SSCMS v7.4.0 contains a reflected cross-site scripting vulnerability in the STL processing endpoint that allows attackers to execute arbitrary JavaScript by crafting malicious STL template payloads that are decrypted and returned without proper sanitization. Attackers can exploit improper output encoding in the /api/stl/actions/dynamic endpoint to inject executable JavaScript into JSON responses, leading to session hijacking, phishing attacks, and unauthorized actions performed on behalf of users.

Title
SSCMS v7.4.0 SQL Injection via stl:sqlContent queryString
Summary
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.

Title
SSCMS v7.4.0 Reflected Cross-Site Scripting via STL Processing
Summary
SSCMS v7.4.0 contains a reflected cross-site scripting vulnerability in the STL processing endpoint that allows attackers to execute arbitrary JavaScript by crafting malicious STL template payloads that are decrypted and returned without proper sanitization. Attackers can exploit improper output encoding in the /api/stl/actions/dynamic endpoint to inject executable JavaScript into JSON responses, leading to session hijacking, phishing attacks, and unauthorized actions performed on behalf of users.
