DescriptionCVE.org

A vulnerability was detected in code-projects Simple IT Discussion Forum 1.0. Impacted is an unknown function of the file /delete-category.php. Performing a manipulation of the argument cat_id results in sql injection. It is possible to initiate the attack remotely. The exploit is now public and may be used.

AnalysisAI

SQL injection in Simple IT Discussion Forum 1.0 by code-projects allows unauthenticated remote attackers to execute arbitrary SQL commands via the cat_id parameter in /delete-category.php, enabling unauthorized data access, modification, or deletion. Publicly available exploit code exists. CVSS 7.3 (High) reflects network-accessible attack surface with low complexity and no authentication requirement, permitting compromise of confidentiality, integrity, and availability.

Technical ContextAI

CWE-89 SQL injection vulnerability stems from insufficient input validation on the cat_id parameter in delete-category.php. Unauthenticated context (PR:N) permits direct database query manipulation through crafted HTTP requests, enabling SELECT, UPDATE, DELETE, or INSERT operations against backend database without access controls.

RemediationAI

No vendor-released patch identified at time of analysis. Primary mitigation: immediately deactivate or restrict access to /delete-category.php until a fix is available. Implement parameterized queries (prepared statements) for all cat_id inputs to prevent SQL injection. Apply input validation with allowlist-only integer constraints for category identifiers. Deploy web application firewall (WAF) rules blocking SQL metacharacters in cat_id parameter. Monitor vendor repository at https://code-projects.org/ for security updates. Restrict administrative functions to authenticated sessions with role-based access controls.
