Description

SignKorn Guestbook contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to the help/de/adminhelp0.php script not properly sanitizing user input supplied to the 'dir_path' variable. This may allow an attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
