Description:
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.
Edit the source code to ensure that input is properly sanitised.
