I'm not entirely sure I get how serious this is. If I understand correctly, you're modifying a .cnt file so that when it's called (by using it's corresponding .hlp file) it will go out and download/execute a program from a predetermined site. When you're at the stage where you can modify files on the target machine, how much of a difference does it make to be able to get a .cnt file to do your bidding, as opposed to any executable that could have another executable bound to it, for example? Perhaps I'm missing something... > -----Original Message----- > From: descript [mailto:descriptat_private] > Sent: Saturday, March 08, 2003 7:38 PM > To: vuln-devat_private; bugtraqat_private > Subject: Win32hlp exploit for : ":LINK overflow" > > > hi list, > > In date Sunday, 9 March, 2003 1:00 AM s0h released an exploit > : Win32hlp exploit for : ":LINK overflow" > > Source : http://s0h.cc/exploit/s0h_Win32hlp.c > Binary : http://s0h.cc/exploit/s0h_Win32hlp.exe > > Discovered by ThreaT <threatat_private>. > Coded by ThreaT <threatat_private> > Hompage : http://s0h.cc/~threat/ > > This exploit can trap a .CNT file (file with .HLP files) with > the arbitrary code who can download and execute a trojan > without user ask. > > This exploit was tested on : > - Windows 2000 PRO/SERVER (fr) SP0 > - Windows 2000 PRO/SERVER (fr) SP1 > - Windows 2000 PRO/SERVER (fr) SP2 > > > Best regards, > descript <descriptat_private> > s0h - Skin of humanity > http://s0h.cc >
