DescriptionCVE.org

A security flaw has been discovered in SSCMS 7.4.0. This vulnerability affects unknown code of the file SitesAddController.Submit.cs of the component DDL Handler. The manipulation of the argument tableHandWrite results in sql injection. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

SQL injection in SSCMS 7.4.0 via the tableHandWrite parameter in SitesAddController.Submit.cs allows authenticated remote attackers to execute arbitrary SQL commands. Public exploit code exists for this vulnerability, and no patch is currently available from the vendor despite early disclosure notification.

Technical ContextAI

The vulnerability is rooted in CWE-89 (SQL Injection), a classic input validation flaw where user-controlled data is concatenated directly into SQL query strings without parameterized query protection or input escaping. SSCMS (a content management system identified via CPE cpe:2.3:a:n/a:sscms) version 7.4.0 fails to properly handle the tableHandWrite parameter in the DDL (Data Definition Language) Handler component within SitesAddController.Submit.cs. This component appears responsible for dynamic schema manipulation, making it a high-risk attack surface. The vulnerability affects the CMS's core data layer, where attackers can inject malicious SQL syntax through a web-accessible controller action.

RemediationAI

Immediate action: Contact the SSCMS vendor directly to obtain a patched version, as vendor responsiveness status is currently unknown despite early disclosure attempts. If a patch is available, upgrade SSCMS to the latest patched release immediately, as SQL injection in a CMS's core database layer poses critical risk. Interim mitigations (if patching is delayed): implement web application firewall (WAF) rules to detect and block SQL injection patterns in the tableHandWrite parameter (e.g., block requests containing SQL keywords like UNION, SELECT, OR, DROP), restrict access to the SitesAddController.Submit endpoint to trusted administrative IP ranges via network-layer access controls, and enable comprehensive SQL query logging and alerting to detect exploitation attempts. Conduct a security audit of other user-input handling in the DDL Handler and SitesAddController components to identify similar injection vulnerabilities.
