Abstract:
=========
An independent vulnerability laboratory researcher discovered a cross site scripting vulnerability in the log analyzer v3.6.0 web application.


Report-Timeline:
================
2012-12-20:    Public or Non-Public Disclosure


Status:
========
Published


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


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


Details:
========
A client side cross-site scripting vulnerability is detected in the LogAnalyzer 3.6.0 web application.
The vulnerability allows an remote attacker with high required user interaction to force client side xss requests.

The vulnerability is located in the asktheoracle.php file with the bound vulnerable oracle_query parameter request.
An attackers can force client side requests to execute arbitrary script code by using the oracle_query parameter.

Successful exploitation of the vulnerability results in client side execution of inject script, client side phishing,
client side module context manipulation and evil unautorized external redirects.

Vulnerable File(s):
                [+] asktheoracle.php

Vulnerable Parameter(s):
                [+] oracle_query


Proof of Concept:
=================
The client side cross site scripting vulnerability can be exploited by remote attackers with medium or high required user interaction
and without privileged application user account.

Note: The 'oracle_query' parameter didn't sanitize properly for asktheoracle.php page.


Solution:
=========
Upgrade to the latest version of Log Analyzer 3.6.1


Risk:
=====
The security risk of the client side cross site scripting web vulnerability is estimated as low(+)
