漏洞:SSL Medium Strength Cipher Suites Supported
The remote host supports the use of SSL ciphers that offer medium
strength encryption. Nessus regards medium strength as any encryption
that uses key lengths at least 64 bits and less than 112 bits, or else
that uses the 3DES encryption suite.
Note that it is considerably easier to circumvent medium strength
encryption if the attacker is on the same physical network.
