CVE-2012-5583: Apereo Phpcas

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

phpCAS before 1.3.2 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.
