Cr@zy_King has discovered a security issue in CS GuestBook, which can be exploited by malicious people to disclose potentially sensitive information.

The security issue is caused due to the user name and password hash being insecurely stored in e.g. /base/usr/0.php inside the web root. This can be exploited to gain knowledge of sensitive information by downloading the file.

The security issue is confirmed in version 1.1 SP1. Other versions may also be affected.

Solution
Restrict access to sensitive files (e.g. through the ".htaccess" file).
