SSL / TLS Certificate Known Hard Coded Private Keys

Medium Nessus Plugin ID 121008

Synopsis

Known SSL / TLS private keys in use.

Description

The remote host is running a service that is using a publicly known SSL / TLS private key.
An attacker may use this key to decrypt intercepted traffic between users and the device.
A remote attacker can also perform a man-in-the-middle attack in order to gain access to the system or modify data in transit.

Solution

Where possible, change the X.509 certificates so that they are unique to the device or contact vendor for guidance.
