CVE-2012-5817 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. Codehaus XFire 1.2.6 and earlier, as used in the Amazon EC2 API Tools Java library and other products, 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.. EPSS estimates a 0.78% chance of exploitation in the next 30 days.
