'Name' => 'Apache Jetspeed Arbitrary File Upload',
'Description' => %q{
This module exploits the unsecured User Manager REST API and a ZIP file
path traversal in Apache Jetspeed-2, versions 2.3.0 and unknown earlier
versions, to upload and execute a shell.

Note: this exploit will create, use, and then delete a new admin user.

Warning: in testing, exploiting the file upload clobbered the web
interface beyond repair. No workaround has been found yet. Use this
module at your own risk. No check will be implemented.
