19
FAUCET Score

CVE-2017-2639 describes a critical vulnerability in Red Hat CloudForms where it fails to validate server hostnames against certificate domain names when communicating with Red Hat Virtualization (RHEV) and OpenShift using a custom CA. This oversight allows an unauthenticated attacker to spoof RHEV or OpenShift systems, potentially leading to the compromise of sensitive information from CloudForms. With a CVSS score of 7.5 (High), this vulnerability has a low attack complexity and high confidentiality impact, requiring no user interaction. There is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is there evidence of active exploitation, and it has received minimal community discussion or media coverage.
