Introduction:
=============
The Endian Firewall is an open source GNU/Linux distribution that specializes on Routing/Firewalling and 
Unified Threat Management. It is being developed by the Italian Endian Srl and the community. Endian is originally 
based on IPCop, which itself was a fork of Smoothwall.

Affected Products:
==================
Endian
Product: UTM Firewall Appliance Application v2.4.x


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium


Details:
========
Multiple non persistent cross site scripting vulnerabilities are detected on Endian Firewall v2.4.x UTM Appliance Application.
The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with high required 
user inter action or local low privileged user account. Successful exploitation can result in account steal, phishing 
& client-side content request manipulation.
