|
|
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.
