This is a modification to the original poisonivy_bof.rb exploit module removing
the need for bruteforce in the case of an unknown server password by
(ab)using the challenge-response as an encryption oracle, making it more reliable.
The vulnerability has also been confirmed in versions 2.2.0 up to 2.3.1 and additional targets for these versions have been added as well.
