Vulnerability AssessmentAI

Risk Assessment	This vulnerability presents elevated real-world risk despite a moderate CVSS v3.1 score of 6.3. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated user (which could be a low-privilege content editor or compromised account) submits a crafted HTTP request to the SitesAddController.Submit endpoint with a malicious SQL payload embedded in the tableHandWrite parameter, such as tableHandWrite=myTable'; DROP TABLE users; --. Since the DDL Handler concatenates this unsanitized input directly into a SQL CREATE/ALTER statement without parameterization, the injected DROP TABLE command executes with the database service's privilege level, destroying the users table or exfiltrating sensitive data. …
Remediation	Immediate action: Contact the SSCMS vendor directly to obtain a patched version, as vendor responsiveness status is currently unknown despite early disclosure attempts. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 30 days: Identify affected systems and apply vendor patches as part of regular patch cycle. …
