CVE-2014-3603: Shibboleth Identity Provider

Medium severity, CVSS 5.9. EPSS: 0.8% chance of exploitation in the next 30 days.

The (1) HttpResource and (2) FileBackedHttpResource implementations in Shibboleth Identity Provider (IdP) before 2.4.1 and OpenSAML Java 2.6.2 do 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.

Affected products

• Shibboleth Identity Provider: before 2.4.1 (fixed in 2.4.1)
• Shibboleth Opensaml Java: before 2.6.2 (fixed in 2.6.2)
