Descriptions

The navigator.sendBeacon implementation in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 omits the CORS Origin header, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site.

La implementación navigator.sendBeacon en Mozilla Firefox anterior a 35.0, Firefox ESR 31.x anterior a 31.4, Thunderbird anterior a 31.4, y SeaMonkey anterior a 2.32 omite la cabecera CORS Origin, lo que permite a atacantes remotos evadir las comprobaciones del control de acceso a CORS y realizar ataques de CSRF a través de un sitio web manipulado.
