SSCMS v7.4.0 SQLi: High-Severity Database Compromise Risk
The National Vulnerability Database has detailed CVE-2026-7435, a critical SQL injection vulnerability impacting SSCMS v7.4.0. This flaw resides within the stl:sqlContent tag, specifically its queryString attribute. The issue stems from the direct integration of this attribute into database queries without any form of parameterization or sanitization.
Attackers can exploit this by crafting encrypted payloads and submitting them to the /api/stl/actions/dynamic endpoint. Successful exploitation enables the execution of arbitrary SQL statements, opening the door to unauthorized database access, data exfiltration, authentication bypass, data manipulation, and even complete database compromise. The National Vulnerability Database assigns this a CVSS score of 7.2 (HIGH), underscoring the severe impact.
This vulnerability represents a direct path to an organization’s crown jewels. Defenders must assume that if an attacker can reach this endpoint, they can own the database. The attacker’s calculus here is straightforward: find an exposed SSCMS instance, craft the payload, and gain full control.
What This Means For You
- If your organization uses SSCMS v7.4.0, prioritize patching or implementing compensating controls immediately. This isn't theoretical; this is a direct path to database compromise. Audit your web application logs for any suspicious activity targeting the `/api/stl/actions/dynamic` endpoint.
