solutions. Flexibly deployed as software, hardware, or a virtual
appliance, SonicWALL GMS offers centralized real-time monitoring, and
comprehensive policy and compliance reporting. For enterprise customers,
SonicWALL GMS streamlines security policy management and appliance
deployment, minimizing administration overhead. Service Providers can

create additional revenue opportunities. For added redundancy and
scalability, GMS can be deployed in a cluster configuration.
(Product description from Website)
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 built-in function to skip the
session check of the web application.
An attacker may exploit this vulnerability by sending a request
to the UMA Interface (/appliance/) with the parameter
"skipSessionCheck=1".
The attacker gains full administrative access to the interface and
could execute code with root or SYSTEM permissions, which leads to
a full compromisation of the system.
Proof of Concept:
=================
http://host/appliance/applianceMainPage?action=status&skipSessionCheck=1
The remote Root/System exploit is attached.
Solution:
=========
Install Hotfix 125076.77. (Download from www.mysonicwall.com)
