Exploit:
/*
\	local ListBox/ComboBox exploit for Win32 
/	
\	Created by xCrZx crazy_einstein yahoo com /11.11.03/
/
\	Usage: MS03-045.exe <-t target> [-r return address]
/
\	there is two targets: CB_DIR (for ComboBox), LB_DIR (for ListBox).
/
\	As to return address it should be such as 0x0000XXYY
/	(and you should know that this address will be transformed
\	into unicode! And if XX and YY bytes <128 it will maintained!
/	And return address will be such as 0x00XX00YY!
\	If not it will be coded in two bytes each of this bytes and
/	return will be looked like 0xZZZZWWWW)
\
/	To figure out handle addresses you can use tools such as
\	Spy++ (default tool contained in MSVC++ 6.0)
/
\	Note: 	there is no so easy exploitation of this stuff!
/		first of all you should figure out the handle
\		addresses of ListBox/ComboBox & EDIT,RichEdit,etc
/		(to store shellcode inside of it.. you can also
\		store shellcode by diffrent way into variables of
/		vuln program (i.e. through fopen(),argv,etc..)

\		    akid, Joel Eriksson, andrewg, Amour and others...
/
\       tested on WinXP (also should work on others Win32)
/
\	p.s. use can find vuln program with SYSTEM privileges (antivirus,firewall,etc)
/            to obtain the SYSTEM privileges
