SynopsisThe remote host may be affected by a vulnerability that allows a remote attacker to potentially decrypt captured TLS traffic.
DescriptionThe remote host supports SSLv2 and therefore may be affected by a vulnerability that allows a cross-protocol Bleichenbacher padding oracle attack known as DROWN (Decrypting RSA with Obsolete and Weakened eNcryption). This vulnerability exists due to a flaw in the Secure Sockets Layer Version 2 (SSLv2) implementation, and it allows captured TLS traffic to by decrypted. A man-in-the-middle attacker can exploit this to decrypt the TLS connection by utilizing previously captured traffic and weak cryptography along with a series of specially crafted connections to an SSLv2 server that uses the same private key.
SolutionDisable SSLv2 and export grade cryptography cipher suites. Ensure that private keys are not used anywhere with server sofware that supports SSLv2 connections.
