CVE-2017-2639 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. It was found that CloudForms does not verify that the server hostname matches the domain name in the certificate when using a custom CA and communicating with Red Hat Virtualization (RHEV) and OpenShift. This would allow an attacker to spoof RHEV or OpenShift systems and potentially harvest sensitive information from CloudForms.. EPSS estimates a 1.14% chance of exploitation in the next 30 days.
