CVE-2012-5806: PayPal Payments Pro

Medium severity, CVSS 5.8. EPSS: 0.6% chance of exploitation in the next 30 days.

The PayPal Payments Pro module in Zen Cart does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, related to use of the PHP fsockopen function, a different vulnerability than CVE-2012-5805.
