This advisory can be found at www.blacktigerz.org Subject: Ocean12 ASP Guestbook Manager v1.00. Description: Written entirely in ASP and VBScript this is a completely web-based, easy to install, ASP Guestbook Program. It stores data in an Access 2000 database and is configured 100% through the web browser, which means an easy installation process. Vendor: Ocean12 Technologies http://www.ocean12tech.com Download: http://scripts.ocean12tech.com/asp/guestbook/ Vulnerability: add.asp neglects filtering user input allowing for script injection to the guestbook via "Name", "E-Mail" and "Massage" fields. The injected script will be executed in anyones browser who visits the guestbook. An attaker may download MS Acces database to gain administrator's password, which is not encrypted at all.
