'Name'=> 'Atlassian Jira Authenticated Upload Code Execution',
'Description' => %q{
This module can be used to execute a payload on Atlassian Jira via
the Universal Plugin Manager(UPM). The module requires valid login
credentials to an account that has access to the plugin manager.
The payload is uploaded as a JAR archive containing a servlet using
a POST request against the UPM component. The check command will
test the validity of user supplied credentials and test for access
to the plugin manager.
