Descriptions
The Erlang otp TLS server answers with different TLS alerts to different error types in the RSA PKCS #1 1.5 padding. This allows an attacker to decrypt content or sign messages with the server's private key (this is a variation of the Bleichenbacher attack).
El servidor TLS en Erlang/OTP responde con alertas TLS diferentes a los diferentes tipos de error en el relleno RSA PKCS #1 1.5. Esto permite que un atacante descifre contenido o firme mensajes con la clave privada del servidor (esta es una variación del ataque Bleichenbacher).
An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle (MiTM) attack, despite the attacker not having gained access to the server’s private key itself.
