Common Vulnerability Scoring System:
====================================
2


Abstract Advisory Information:
==============================
The Vulnerability Laboratory Research Team discovered a client side web vulnerability in the Pan-Tilt Wireless Network Camera web application interface.


Vulnerability Disclosure Timeline:
==================================
2012-12-26:	Public or Non-Public Disclosure


Discovery Status:
=================
Published


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


Severity Level:
===============
Low


Technical Details & Description:
================================
Multiple cross site scripting vulnerabilities are detected in the Pan-Tilt Wireless Network Camera web application with the marmitek interface.

A non persistent web vulnerability allows to manipulate via client side forced browser requests to phish accounts and manipulate client side 
ip camera web module context. The vulnerabilities are located in the view.cgi and setup.cgi files when processing to request the bound vulnerable 
language or page parameters. The vulnerability can be exploited in all medium outdoor ip cams of the marmitek vendor and the bound suppliers.

Exploitation of the vulnerability requires medium or high user interaction and no privileged web application user account. Successful exploitation 
results in non -persistent account phishing attacks, client side camera manipulation or client side vulnerable module web context manipulation. 

Vulnerable File(s):
				[+] view.cgi
				[+] setup.cgi

Vulnerable Parameter(s):
				[+] language
				[+] page


Proof of Concept (PoC):
=======================
The client side cross site scripting vulnerabilities can be exploited by remote attackers without required application user account and 
with medium or high user interaction. For demonstration or reproduce ...

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a restriction and secure parse of the vulnerable language & page parameter requests in the view- and setup.cgi files.


Security Risk:
==============
The security risk of the client side cross site scripting vulnerabilities are estimated as medium(-).
