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.
