CVE-2012-5805 is a vulnerability of currently unknown severity. The PayPal IPN functionality 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, a different vulnerability than CVE-2012-5806.. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
