Aquifer CMS contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'Keyword' variable upon submission to the 'Public/Index.asp' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 3.7 or higher, as it has been reported to fix this vulnerability. In addition, Liquid Development, LLP has released a patch for older versions in the 3.x line.
