Secunia

Micheal Turner has discovered a weakness in phpSysInfo, which can be exploited by malicious people to detect files on the server.

The weakness is caused by an error message returning information about whether or not a file exists. This can be exploited by providing a filename with a directory traversal character sequence to the "lng" parameter in index.php.

The weakness has been confirmed in version 2.5.1. Other versions may also be affected.

Solution
Filter malicious characters or character sequences with a web proxy.
