Synnergy Laboratories Advisory SLA-2000-17
NAME
Anaconda Foundation Directory NULL byte vulnerability
AFFECTED
Linux/UNIX with Anaconda Foundation Directory
SYNOPSIS
Synnergy Labs has found a flaw within Anaconda Foundation Directory
that allows a user to successfully traverse the filesystem on a
remote host, allowing arbitary files/folders to be read.
DESCRIPTION
The Anaconda Foundation Directory is a Yahoo style search engine
based on the Open Directory project, www.dmoz.org. The Anaconda
Foundation Directory allows you to dynamically integrate content
into your site's own look and feel. This is the exact same content
that Lycos features on their front page! Product pricing is $499 US.
Anaconda Foundation Directory can be found
at:http://anacondapartners.com/ap_afodpdemo.shtml
Synnergy has recently discovered a flaw within Anaconda Foundation Directory that allows a remote
user to traverse the filesystem as a request to the script using the $template=_some_file_. It is
then possible to read any file contents with priviledges as the httpd.
Although the script checks for the file extension (.htm, .html, .shtml, .stm) adding a trailing
%00.html, (a NULL byte in URL encoded format), at the end of the request will force the script to
open the file.
Example:
http://www.target.com/cgi-bin/apexec.pl?etype=odp&template=../../../../../../../../../etc/resolv.conf%00.html&passurl=/category/
The above line if given will output the file contents of
/etc/resolv.conf.
SOLUTION
The vendors have been informed of the bug. It is advised to wait
for the next patched version of Anaconda Foundation Directory to be
released.
