一个牛人写的攻击程序
/*
\ local ListBox/ComboBox exploit for Win32
/
\ Created by xCrZx [crazy_einstein@yahoo.com] /11.11.03/
/
\ Usage: 85boomerang.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..)
\
/ Bug info: http://www.microsoft.com/technet/treeview/default.
asp?url=/technet/security/Bulletin/MS03-045.asp

\ yesh yesh y0...check it out y0...
/ wu-tang clan forever :)
\
/ greetzz to: tANDm :), Billi_k1d, alph4, btr, hhs, v1pee, ni69az,
\ 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

\ exploit:

\ [85boomerang local exploit by xCrZx /11.11.03/]

\ Enter addresses of the program handles:

ListBox/ComboBox>
\ (i.e. "00450ca1 0066345c") -> 1e01f6 2701a2

因为骄傲
使它失去方向
它本想冲入云霄
