| Anonymous Diffie-Hellman Key Exchange MitM Vulnerability
| State: VULNERABLE
| Transport Layer Security (TLS) services that use anonymous
| Diffie-Hellman key exchange only provide protection against passive
| eavesdropping, and are vulnerable to active man-in-the-middle attacks
| which could completely compromise the confidentiality and integrity
| of any data exchanged over the resulting session.
