iPei Guestbook XSS vuln.

iPei Guestbook XSS vuln.

Vuln. discovered by : r0t
Date: 30 dec. 2005
vendor:http://www.epistream.com/ipei/
affected version:v1.7 and prior

Product Description:

iPei is a simple but elegant little guestbook. The interface is OS X gui-ish, and it comes with mundane features like pass word protection, IP view, entry pruning, commenting, Y! smilies, secure posting, and owners may customize some aspects of displays.


Vuln. Description:

iPei Guestbook contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to email field paremters in "/index.php?a=sign" isn't properly sanitised before being returned to the user.
This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.


Solution:
Edit the source code to ensure that input is properly sanitised.
