VERIFY ADVISORY:
https://secunia.com/advisories/38855/
DESCRIPTION:
liscker has discovered a vulnerability in BBSXP, which can be
exploited by malicious people to conduct cross-site scripting
attacks.
Input appended to the URL after e.g. AddPost.asp, AddTopic.asp,
Admin_Default.asp, Bank.asp, Manage.asp, and ShowPost.asp is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in the context of an affected site.
The vulnerability is confirmed in version 2008 SP2. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
