OpenSSL 1.0.2 < 1.0.2f Information Disclosure

Low Nessus Network Monitor Plugin ID 9465


The remote web server is running an outdated instance of OpenSSL and that is affected by an Information Disclosure vulnerability.


According to its banner, the version of OpenSSL on the remote host is 1.0.2 prior to 1.0.2f and is affected by a flaw in the 'DH_check_pub_key()' function in 'crypto/dh/dh_check.c' that is triggered when generating DH parameters based on unsafe primes. By completing multiple handshakes with a peer, a remote attacker can potentially disclose the peer's private DH exponent.


Upgrade OpenSSL to version 1.0.2f or higher.
