Descriptions

NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery (CSRF) attacks. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

Los plugins NPAPI, como Adobe Flash, pueden enviar peticiones cross-origin, omitiendo CORS al hacer un POST same-origin que realiza una redirección 307 al sitio objetivo. Esto permite que un sitio malicioso se vea envuelto en ataques Cross-Site Request Forgery (CSRF). La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 60 y la 52.9, Firefox ESR en versiones anteriores a la 60.1 y la 52.9 y Firefox en versiones anteriores a la 61.

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, bypass CORS restrictions, obtain sensitive information, or execute arbitrary code. It was discovered that S/MIME and PGP decryption oracles can be built with HTML emails. An attacker could potentially exploit this to obtain sensitive information. Various other issues were also addressed.
