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.

The Authorize.Net eCheck 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.

The LinkPoint 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.

The traverseStrictSanitize function in admin_dir/includes/classes/AdminRequestSanitizer.php in ZenCart 1.5.5e mishandles key strings, which allows remote authenticated users to execute arbitrary PHP code by placing that code into an invalid array index of the admin_name array parameter to admin_dir/login.php, if there is an export of an error-log entry for that invalid array index.

Zen Cart 1.6.0 has XSS in the main_page parameter to index.php. NOTE: 1.6.0 is not an official release but the vendor's README.md file offers a link to v160.zip with a description of "Download latest in-development version from github."
