CVE-2012-5486

Advisory

Plone 4.3 includes a fix for CVE-2012-5486: It was discovered that Plone, included as a part of luci, did not properly sanitize HTTP headers provided within certain URL requests. A remote attacker could use a specially crafted URL that, when processed, would cause the injected HTTP headers to be returned as a part of the Plone HTTP response, potentially allowing the attacker to perform other more advanced attacks.
