Descriptions

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.

Se ha detectado que CloudForms no verifica que el nombre de host del servidor coincida con el nombre de dominio en el certificado cuando se utiliza una CA personalizada y se comunica con Red Hat Virtualization (RHEV) y OpenShift. Esto permitiría a un atacante falsificar sistemas RHEV u OpenShift y potencialmente obtener información sensible de CloudForms.

Red Hat CloudForms Management Engine delivers the insight, control, and automation needed to address the challenges of managing virtual environments. CloudForms Management Engine is built on Ruby on Rails, a model-view-controller framework for web application development. Action Pack implements the controller and the view components. Security Fix: CloudForms includes a default SSL/TLS certificate for the web server. This certificate is replaced at install time, however if an attacker were able to man-in-the-middle an administrator while installing the new certificate the attacker could get a copy of the private key uploaded allowing for future attacks.
