Description
This module exploits a cross-site request forgery (CSRF) vulnerability
in F5 Big-IP's iControl interface to write an arbitrary file to the
filesystem.
While any file can be written to any location as root, the
exploitability is limited by SELinux; the vast majority of writable
locations are unavailable. By default, we write to a script that
executes at reboot, which means the payload will execute the next time
the server boots.
An alternate target - Login - will add a backdoor that executes next
time a user logs in interactively. This overwrites a file,
but we restore it when we get a session
Note that because this is a CSRF vulnerability, it starts a web
server, but an authenticated administrator must visit the site, which
redirects them to the target.
