Descriptions

The AWS S3 Crypto SDK sends an unencrypted hash of the plaintext alongside the ciphertext as a metadata field. This hash can be used to brute force the plaintext, if the hash is readable to the attacker. AWS now blocks this metadata field, but older SDK versions still send it.

AWS S3 Crypto SDK envía un hash no cifrado del texto plano junto con el texto cifrado como un campo de metadatos. Este hash se puede utilizar para forzar el texto plano, si el hash es legible para el atacante. AWS ahora bloquea este campo de metadatos, pero las versiones anteriores del SDK aún lo envían.
