The remote service is affected by multiple vulnerabilities.
According to its banner, the remote host is running a version of
OpenSSL 1.0.1 prior to 1.0.1r. It is, therefore, affected by the
following vulnerabilities :
- A cipher algorithm downgrade vulnerability exists due to
a flaw that is triggered when handling cipher
negotiation. A remote attacker can exploit this to
negotiate SSLv2 ciphers and complete SSLv2 handshakes
even if all SSLv2 ciphers have been disabled on the
server. Note that this vulnerability only exists if the
SSL_OP_NO_SSLv2 option has not been disabled.
- A man-in-the-middle vulnerability, known as Logjam,
exists due to a flaw in the SSL/TLS protocol. A remote
attacker can exploit this flaw to downgrade connections
using ephemeral Diffie-Hellman key exchange to 512-bit
export-grade cryptography. (CVE-2015-4000)
