Abstract:
=========
A Vulnerability Lab Researcher discovered multiple persistent web vulnerabilities on eFronts Community ++ v3.6.10 Application.


Report-Timeline:
================
2012-02-07:	Public or Non-Public Disclosure


Status:
========
Published


Affected Products:
==================
eFront
Product: Communiy ++ v3.6.10


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


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


Details:
========
Multiple persistent input validation vulnerabilities are detected on eFronts Community++ application v3.6.10.
The vulnerability allows an remote attacker or local low privileged user account to inject/implement malicious 
persistent script code. Successful exploitation with low required user inter action can result in session hijacking 
or persistent context manipulations.
