SSL Null Cipher Suites Supported

medium Nessus Plugin ID 66848

Synopsis

The remote service supports the use of null SSL ciphers.

Description

The remote host supports the use of SSL ciphers that offer no encryption at all.

Note: This is considerably easier to exploit if the attacker is on the same physical network.

Solution

Reconfigure the affected application, if possible to avoid the use of null ciphers.
