SSL Certificate Signed with the Compromised FortiGate Key
Medium Nessus Plugin ID 62969
Synopsis
The SSL certificate for this service was signed by a certificate authority (CA) whose private key has been compromised.
Description
The X.509 certificate of the remote host was signed by a certificate belonging to a Certificate Authority (CA) found in FortiGate devices.
The private key corresponding to the CA has been compromised, meaning that the remote host's X.509 certificate cannot be trusted.
Certificate chains descending from this CA could allow an attacker to perform man-in-the-middle attacks and decode traffic.
Solution
Configure the device to use a device-specific CA certificate.
