CVE-2017-2639: Redhat cloudforms improper certificate validation vulnerability

Redhat · Cloudforms

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.
