Descriptions

POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

Las peticiones POST realizadas por complementos de NPAPI, tal y como Flash, que reciben una respuesta de redireccionamiento del estado 308 pueden pasar por alto los requerimientos de CORS. Esto puede permitir a un atacante realizar ataques de tipo Cross-Site Request Forgery (CSRF). Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.8, Firefox anterior a versión 68 y Thunderbird anterior a versión 60.8.
