Acuity CMS 2.6.x (ASP) XSS vuln.

Acuity CMS 2.6.x (ASP) XSS vuln.

Vuln. discovered by : r0t
Date: 17 dec. 2005
vendor:http://www.acuitycms.com/
affected version:2.6.2

Product Description:

Acuity CMS is a highly affordable, very easy to use content management system that offers a rich set of features despite its low price point. Advanced WYSIWYG editing (using Acuity Visual Editor), advanced code cleaning, menu management, integrated search, and much more. Although targeted at small to medium business, Acuity CMS can run very large and interactive websites.

Vuln. Description:

Acuity CMS contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to search module paremters isn't properly sanitised before being returned to the user.
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.

+
note: also "page" paramter isn't properly sanitised after some unsanitised input form user will get error like:

Microsoft VBScript runtime error '800a000d'

I dont think that is vuln, but ...

Solution:
Edit the source code to ensure that input is properly sanitised.
