Medium Nessus Network Monitor Plugin ID 9464

Synopsis

The remote web server is running an outdated instance of OpenSSL and that is affected by an Information Disclosure vulnerability.

Description

According to its banner, the version of OpenSSL on the remote host is 1.0.2 prior to 1.0.2f or 1.0.1 prior to 1.0.1r and is affected by a flaw that is triggered when handling cipher negotiation. This may allow a remote attacker to negotiate SSLv2 ciphers that are disabled on the server.
