CVE-2012-5486: XSS

First published: Wed Nov 21 2012(Updated: )

A HTTP header injection flaw was found in the way Plone, a user friendly and powerful content management system, performed sanitization of HTTP headers provided within certain URL requests. A remote attacker could provide a specially-crafted URL that, when processed would lead the injected HTTP headers to be returned as part of Plone system HTTP response (possibly leading to HTTP response splitting, cross-site scripting [XSS] flaws, session fixation or unauthorized HTTP redirect attacks - to mention some of the possible negative consequences).
