|
|
This module allows execution of native payloads from a privileged Firefox Javascript shell.
|
|
It places the specified payload into memory, adds the necessary protection flags,
|
|
and calls it, which can be useful for upgrading a Firefox javascript shell to a Meterpreter
|
|
session without touching the disk.
