The remote web server contains a script that is vulnerable to a SQL injection attack.
The remote host is running Serendipity. Serendipity is a blogging software that is implemented in PHP. This version of Serendipity is vulnerable to a remote SQL Injection attack. Specifically, the 'url_id' parameter of the exit.php script does not properly parse out SQL reserved characters. An attacker exploiting this flaw would send a malformed query to the exit.php script. Successful exploitation would result in the attacker being able to read data, write data, and possibly execute arbitrary commands.
Upgrade to version 0.72 or higher.
