Personally, I know people who know that they shouldn't download or open .exe's due to viruses, yet they would have no clue about .cnt or .hlp files. That being said it could be a risk for them, yet people with some experience would noticed that something isn't right and ignore it... But that's just me.... I could have it wrong also, but does the risk happen because the .cnt can be emailed to someone/sent to them, and they could download and run it? That's how I see it working anyways, just like running an executable from an email. - Josh -----Original Message----- From: Rob Shein [mailto:shotenat_private] Sent: Tuesday, March 11, 2003 8:59 AM To: 'descript'; vuln-devat_private; bugtraqat_private Subject: RE: Win32hlp exploit for : ":LINK overflow" 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 >
