CVE-2012-4948: Fortinet Fortigate-1000c

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
