|
|
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 has been used.
