Highly customizable guestbook that was released on Feb. 20, 2002, and can be downloaded at http://www.levcgi.com/programs.cgi?program=myguestbook

Vulnerable (tested) Versions:

Vendor Contact:

4-28-02 - Emailed lev@taintedthoughts.com

4-30-02 - No Reply from the author and I have decided not to wait since I never got a reply about another concern i had several months ago involving one of his cgi scripts.

Vulnerability:

myguestbook inproperly filters input to the guestbook making the guestbook prone to cross-site scripting attacks by malicious visitors to the site. This could be a medium to high concern when mixed with a website that uses cookies.
