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


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


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


Authentication Type:
====================
Pre Auth (No Privileges or Session)


User Interaction:
=================
Low User Interaction


Disclosure Type:
================
Full Disclosure


Technical Details & Description:
================================
The vulnerability is located in the filterSearch and filterSearchType parameters of the jobmgr.cgi file.
Remote attackers are able to inject own malicious script code to manipulate client-side application requests 
to compromise user session data. The request method to inject is GET and the attack vector is non-persistent.

Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, 
non-persistent external redirects to malicious source and non-persistent manipulation of affected application modules.

Vulnerable Module(s):
[+] Search

Vulnerable File(s):
[+] jobmgr.cgi

Vulnerable Parameter(s):
[+] filterSearch
[+] filterSearchType


Proof of Concept (PoC):
=======================
The client-side cross site scripting web vulnerability can be exploited by remote attackers without account and with low user interaction.
For security demonstration or to reproduce the cross site web vulnerability follow the provided information and steps below to continue.
