DescriptionCVE.org

A vulnerability was determined in code-projects Simple IT Discussion Forum 1.0. The impacted element is an unknown function of the file /pages/content.php. This manipulation of the argument post_id causes sql injection. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.

AnalysisAI

SQL injection in code-projects Simple IT Discussion Forum 1.0 allows unauthenticated remote attackers to extract, modify, or delete database records via the post_id parameter in /pages/content.php. Publicly available exploit code exists. The vulnerability enables unauthorized database access with low complexity, requiring no user interaction. Attack achieves limited confidentiality, integrity, and availability impact across the vulnerable application.

Technical ContextAI

CWE-89 SQL injection originates from insufficient input validation on the post_id parameter passed to /pages/content.php. The application directly incorporates user-supplied input into SQL queries without proper sanitization or parameterized statements, allowing attackers to manipulate database logic. CVSS vector confirms network-accessible, low-complexity exploitation requiring no privileges (PR:N).

RemediationAI

No vendor-released patch identified at time of analysis. Upstream project status via https://code-projects.org/ should be verified for updates. Immediate mitigations: implement parameterized queries or prepared statements for all database interactions in /pages/content.php, apply strict input validation with allowlisting on post_id parameter accepting only integer values, deploy web application firewall rules blocking SQL metacharacters in query strings. Organizations should consider deactivating the forum application until vendor provides security updates. Monitor VulDB advisory https://vuldb.com/vuln/356276 and GitHub disclosure https://github.com/lonelyuan/vunls/issues/6 for remediation guidance. Review database access logs for exploitation attempts targeting content.php with malformed post_id values.
