Exploit Demo – FreeFloatFTPd Remote SYSTEM. Oppa Stuxnet Style!

Ever since Kingcope released the “Stuxnet Style” MySQL exploit using .mof files to execute dropped binaries, illness there has been a rash of similar exploits cropping up – and I fully expect many more to come. This one is one of the interesting ones, as it demonstrates something extremely interesting. How improper FTP file access privileges can lead to trivial remote code execution.

This exploit works in an extraordinarily simple manner. The FreeFloat FTP Server is rife with security flaws. Not least the fact it has no authentication whatsoever, and drops one right into C: with privileges to write files as the SYSTEM user.

It uploads the binary (Meterpreter in the MSF exploit) to System32, then plants a .MOF file to execute it in the System32wbemmof directory, allowing Windoes Management Interface to execute it as SYSTEM – the same as the other exploits.

Essentially, you pop a SYSTEM shell within less than a minute.

I expect that future weeks will show us more and more “Stuxnet Style” exploits as this technique becomes more trendy, hence, “Oppa Stuxnet Style!”.

Without further ado, here is the video!
