SSL Certificate Signed with the Compromised FortiGate Key

Medium Nessus Plugin ID 62969


The SSL certificate for this service was signed by a certificate authority (CA) whose private key has been compromised.


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.


Configure the device to use a device-specific CA certificate.
