directorypro.cgi , directory traversal

[Marshal <marshal () marshal-soft com>]

cgi-script directorypro.cgi is vulnerable to a directory traversal.

http://target/cgi-bin/directorypro.cgi?want=showcat&show=../../../..//etc/motd%00

I didn't looked at the source of the script but it is probably a script
wat normally puts an extension to the requested file.
But bij putting the %00 (NULL) character at the end of your request you
can
bypass this. The extension will be appended but the string is read till
a
NULL character is found, so before the extension.

Didn't find any report of this bug on securityfocus and google.
And didn't inform vendor because i don't know who it is =)

Greetings
