To: BUGTRAQ@SECURITYFOCUS.COM

Hi,

Date: 2000/11/20
Affected Application: CGIForum 1.0
	http://www.marcbrinkmann.de/inandonline/netz/CGIForum-1.0.tar.gz

CGIForum is a free forum. We can set 'thesection' parameter to view
files on the vulnerable system with privileges of the user "nobody".

This is caused from OutputHTMLFile function in cgiforum.pl script where $section (= $thesection )  isn't checked (never besides in this script).

e.g.:
http://127.0.0.1/cgi-bin/cgiforum.pl?thesection=../../../../../../etc/passwd%00

The author is informed.
