|
||||
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.
