CVE-2012-5799: Prestashop

Medium severity, CVSS 5.8. EPSS: 0.8% chance of exploitation in the next 30 days.

The Canada Post (aka CanadaPost) module in PrestaShop 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.
