CVE-2011-5240: Magentocommerce Magento

Medium severity, CVSS 5.8. EPSS: 0.6% chance of exploitation in the next 30 days.

Magento 1.5 and 1.6.2 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.
