        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.
