Vuln. Description.

Toast Forums contains a flaw that allows a remote cross site scripting
attack. This flaw exists because input passed to
"author","subject","message","dayprune" 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.

-1&author=r0t&subject=[XSS]

/toast.asp?action=posts&sub=search&fid=
-1&author=r0t&subject=&message=[XSS]

/toast.asp?action=posts&sub=search&fid=
-1&author=r0t&subject=&message=&dayprune=[XSS]

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