CVE-2014-4741

Vulnerability

xClassified version 1.2 is vulnerable to SQL injection through the catid parameter in the /demo/ads.php script. The application fails to properly sanitize user-supplied input before constructing SQL queries, allowing an attacker to inject malicious SQL statements [1].

Exploitation

An attacker can exploit this vulnerability without authentication by sending a crafted HTTP GET request to the vulnerable endpoint. The catid parameter is directly passed into a SQL query without sanitization. By appending SQL injection payloads, such as ' OR '1'='1 or UNION-based queries, the attacker can manipulate the database query logic [1].

Impact

Successful exploitation allows an attacker to execute arbitrary SQL commands on the underlying database. This can lead to unauthorized access to sensitive data, including usernames, passwords, and other stored information. The attacker may also be able to modify or delete data, potentially compromising the entire application [1].

Mitigation

As of the publication date (2014-07-09), no patched version has been released for xClassified 1.2. Users should apply input validation and parameterized queries to the catid parameter as a workaround. Given the software's age and apparent lack of maintenance, upgrading to a modern, securely developed alternative is strongly recommended [1].
