SSCMS Path Traversal and Injection

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.

A path traversal vulnerability exists in SSCMS versions up to 7.4.0 within the PathUtils.RemoveParentPath function of the plugin download API endpoint (/api/admin/plugins/install/actions/download). An authenticated administrator with high privileges can manipulate the path argument to traverse the file system and access or modify files outside the intended directory, potentially leading to information disclosure or system compromise. The vulnerability has public proof-of-concept code available, though the CVSS score of 3.8 is relatively low due to the requirement for authenticated administrative access, making this a lower-priority but still exploitable issue in environments where admin credentials may be compromised.
