Mozilla Foundation Security Advisory 2009-22

Title: Firefox allows Refresh header to redirect to javascript: URIs
Impact: Moderate
Announced: April 21, 2009
Reporter: Michael
Products: Firefox, SeaMonkey

Fixed in: Firefox 3.0.9
Description

Mozilla community member Michael reported that when a server responds with a Refresh header containing a javascript: URI, Firefox will redirect to the javascript: URI. If an attacker could inject a Refresh header into a server response, or could control the value that a site places in the Refresh header, they could use this vulnerability to perform an XSS attack and execute arbitrary JavaScript within the context of that site.
