WHMCompleteSolution XSS vuln.

WHMCompleteSolution XSS vuln.
Vuln. dicovered by : r0t
Date: 14 dec. 2005
vendor:http://www.whmcs.com/
affected version:2.1 and prior

Product Description:

WHMCompleteSolution has the features that all web hosts are looking for. Integrated directly with the WHM and cPanel server management software, your WHMCS System will provide you with automated account creation, suspension and termination aswell as keeping track of all clients including their hosting accounts and domains and all due payment dates associated with these. It also allows you to send mailings to individual clients or selected clients in mass with mail merge features to customise the messages. Not only does it handle clients, but it also has an integrated support system including a ticket system which supports attachments, knowledgebase, announcements and downloads.


Vuln. Description:

contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to search parameters in "knowledgebase.php" 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.

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