Siteminder is vulnerable to XSS whereby a user can tag HTML or
javascript on to various locations
in a URL or input field and have the script run in the local users
browser. This can be used to
perform phishing attacks, hijack users browser sessions or user
account information by redrawing
the login page of a site.

The following link will abuse the URL option by first logging the
user out of the site with a
timeout error, due to the fact that we send her off to another HTTPS
site, taking the user back to
the login page. Next, we open an IFRAME over the original login
fields with malicious Username and
Password input fields, whereby a user will then supply their login
details to a malicious site,
to be later harvested and used in an attack.

To test if you are vulnerable to this issue, you can tag the
following on to the end of a
siteminder URL. If it is successful, you should see the Google
homepage within an IFRAME.
