SSL Null Cipher Suites Supported

medium Nessus Plugin ID 66848
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
