Synopsis

The remote server is vulnerable to man-in-the-middle attacks.

Description

According to its banner, the remote server is running a version of OpenSSL that is earlier than 0.9.7h or 0.9.8a.

If the SSL_OP_MSIE_SSLV2_RSA_PADDING option is used, a remote attacker could force a client to downgrade to a weaker protocol and implement a man-in-the-middle attack.

Solution

Upgrade to OpenSSL 0.9.7h / 0.9.8a or later.
