  COWS Contains Multiple Security Vulnerabilities
------------------------------------------------------------------------

SUMMARY

 <http://www.cows.co.uk/> COWS (CGI Online Worldweb Shopping) is an easy
to use solution for e-commerce. The product has been found to contain
multiple security vulnerabilities ranging from cross-site scripting, to
path disclosure.

DETAILS

The COWS scripts contain several CGIs that are vulnerable to attack:

diagnose.cgi and compatible.cgi
Both these scripts when accessed give a wealth of information on the
remote host. Further, a vulnerability in them allows remote attackers to
exploit a cross-site scripting vulnerability in the product causing it to
return unfiltered HTML and JavaScript code.

Example:
/diagnose.cgi?<script>MALICIOUS SCRIPT</script>
Or
/compatible.cgi?<script>MALICIOUS SCRIPT</script>.

browse-no-frames.pl
When the CGI is access with a malformed URL, an error will return, the
error page will contain the full path where the CGI is located.

Example:
/browse-no-frames.pl?group=path%20disclosure
