DescriptionCVE.org

A vulnerability was identified in code-projects Online Complaint Site 1.0. This vulnerability affects unknown code of the file /cms/users/index.php. Such manipulation of the argument Username leads to sql injection. The attack may be performed from remote. The exploit is publicly available and might be used.

AnalysisAI

SQL injection in code-projects Online Complaint Site 1.0 allows authenticated remote attackers to manipulate the Username parameter in /cms/users/index.php and execute arbitrary SQL queries with limited impact to confidentiality, integrity, and availability. The CVSS 2.1 score and 0.03% EPSS percentile indicate low real-world risk despite public exploit availability, likely due to the authentication requirement (PR:L) and constrained impact scope.

Technical ContextAI

The vulnerability is a SQL injection flaw (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affecting a PHP application endpoint. The issue stems from unsanitized user input in the Username parameter passed to /cms/users/index.php without proper parameterized query usage or input validation. The affected product is a complaint management system (cpe:2.3:a:fabian:online_complaint_site:1.0:*:*:*:*:*:*:*) developed by fabian, suggesting a small-scale or educational web application rather than enterprise software.

RemediationAI

No vendor-released patch identified at time of analysis. Immediate remediation requires either upgrading to a patched version from the developer (if available) or implementing input validation and parameterized queries in the Username parameter handler. Specific compensating controls: (1) Apply Web Application Firewall (WAF) rules to detect and block SQL injection payloads in the Username field (trade-off: false positives may block legitimate usernames with special characters); (2) Restrict /cms/users/index.php access by IP allowlist to authorized administrators only (trade-off: reduces operational flexibility for remote administration); (3) Enforce prepared statements and stored procedures in the PHP code if source is available. Contact code-projects.org for patch availability status. Monitor vuldb.com entry #327639 for updates.
