CVE-2012-5799

Status: ModifiedMedium (5.8)—

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.
