IntranetApp XSS vuln.

IntranetApp XSS vuln.

Vuln. discovered by : r0t
Date: 21 dec. 2005
vendor:www.aspapp.com/content.asp?contentid=322
affected version:3.3 and prior

Product Description:

IntranetApp gets groups on the same page with tools to enhance collaboration and communication. With this pre-built application you can create and manage company employees, news, events, projects, tasks, Web resources, documents and discussion forums. IntranetApp is completely Web based and customizable. Full source code (standard .asp) included.

Vuln. Description:

IntranetApp contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "ret_page" paremter in "login.asp" and "do_search" "search" in "content.asp" 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.

example:

/login.asp?ret_page=[XSS]

/content.asp?CatId=&ContentType=
&keywords=r0t&search=%3E&do_search=[XSS]

/content.asp?CatId=&ContentType=&
keywords=r0t&search=[XSS]

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