G5 Scripts Guestbook PHP 1.2.8 – Cross-Site Scripting
[:::::::::::::::::::::::::::::::::::::: 0x1 ::::::::::::::::::::::::::::::::::::::] >> General Information Advisory/Exploit Title = Guestbook PHP XSS Vulnerability Author = Valentin Hoebel Contact = valentin@xenuser.org [:::::::::::::::::::::::::::::::::::::: 0x2 ::::::::::::::::::::::::::::::::::::::] >> Product information Name = Guestbook PHP Vendor = G5 Scripts Vendor Website = http://www.g5-scripts.de Affected Version(s) = 1.2.8 [:::::::::::::::::::::::::::::::::::::: 0x3 ::::::::::::::::::::::::::::::::::::::] >> #1 Vulnerability Type = XSS Affected Input Boxes = "Name", "Vorname", "Land", "Message" The guestbook fails to properly sanitize the user input when a new entry is added. When HTML/Java Script code is added, it gets displayed/parsed when the new entry was successfully submitted. Furthermore the code gets executed when the admin views the entries in the control panel. It is even possible to temporarily disable the admin features in the backend since the injected code gets executed before the admin buttons get displayed. When the correct code was injected, the design gets destroyed and the admin buttons disappear.
