Description

The default configuration of Fortinet Fortigate UTM appliances uses the same Certification Authority certificate and same private key across different customers' installations, which makes it easier for man-in-the-middle attackers to spoof SSL servers by leveraging the presence of the Fortinet_CA_SSLProxy certificate in a list of trusted root certification authorities.
