CVE-2012-5805
Zen Cart PayPal IPN - Certificate Hostname Validation Bypass
Title source: llmDescription
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.
