erlang: TLS server vulnerable to Adaptive Chosen Ciphertext attack allowing plaintext recovery or MITM attack
Published Dec 12, 2017
6.5
MEDIUMCVSS 3.0
EPSS 22.10%
Description
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).
