--AFFECTED SOFTWARE--------------------------

Name: phpWebSite
Version: 1.4.0
Release date: Dec 11, 2007

Developed by the Web Technology Group at Appalachian State University,
phpWebSite provides a complete web site content management system ( CMS ).
All client output is XHTML 1.0 and meets the
W3C's Web Accessibility Initiative requirements.

--DISCUSSION---------------------------------

The phpWebSite CMS is vulnerable to a Non-Persistent (or reflected)
Cross-Site Scripting attack. The problem exists because of the lack
of properly escaping user input before using it to generate links on
the search result page.
