iPei Guestbook XSS vuln.
Vuln. discovered by : r0t
Date: 30 dec. 2005
orginal advisory:http://pridels.blogspot.com/2005/12/ipei-guestbook-xss-vuln.html
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.
