Code-Projects Online Complaint Site SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Online Complaint Site version 1.0. The issue arises in the file '/cms/users/index.php', where the 'username' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, with public proof-of-concept available.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation of data, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/cms/users/index.php' with the 'username' parameter. Injecting a payload that exploits time-based blind SQL injection, such as one that uses the MySQL 'SLEEP' function, can demonstrate the vulnerability.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
