The logjam is a security vulnerability against a Diffie–Hellman key exchange. It ranges from 512-bit to 1024-bit keys. It was publicly reported on May 20, 2015, by a group of scientists. This server support is vulnerable to DHE_EXPORT and thus this server is vulnerable to Logjam attack. This type of attack allows a man in the middle attacker to downgrade vulnerable TLS connections to 512-bit export grade cryptography. This allows the attacker to read and modify any data passed over the connection.
Using this vulnerability, an attacker can:-
