## Auction Weaver 1.02 / Only confirmed with LITE
## - Proof of Concept exploit -
##
## CGI Script Center have just released an update
## of Auction Weaver due to security reasons - I
## suggest that you spend some more time securing
## it, and the other scripts - It is really needed.
##
## This exploit will spawn a xterm from $target
## to $attacker, thanks to a unsecure open(..)
## in the script.
##
## This exploit will not work on hosts running
## Auction Weaver on NT, due to the xterm call.
##
## CGI Script Center, please contact me if you need
## help with securing your scripts...
