The hhp presents... The hhp-pine remote exploit advisory. 6/22/99 By: loophole of hhp. http://hhp.perlx.com/ #---------------------------------------------------------# A few months ago I found a bigger problem with the charset bug then imagined. With a uuencode/uudecode method in the charset, and an index.html of a site, it's possible to run any program/script wanted to on the remote system. When the email is read it launches lynx -source and grabs the index.html which is then uudecoded and ran. This includes root and non-root users infected. Many big servers run pine, and having fingerd running, most of the time allows us complete access to get every username on the server, which then is simple to send the infected emails to each user. We have tested this on our own systems with full success. These operating systems include BSD, Linux, IRIX, AIX, SCO, and SunOS. I'm sure this will be fixed in the newer version along with the patch already made for the current version. hhp-pine.tar is available to download at our site, http://hhp.hemp.net/. The current pine 4.10 patch is available to download at http://www.geek-girl.com/bugtraq/1999_1/0532.html Jobs/Probs/Bugs/Etc. -> loophole@hhp.perlx.com #---------------------------------------------------------#
