Summary

A vulnerability in a Kubernetes component used by Micro Focus CDF platform was addressed by Micro Focus Service Management Automation (SMA). The vulnerability which originates from the Kubernetes component, could be exploited to allow unauthorized modification of data and Denial of Service. However, after analysis, Micro Focus R&D teams have determined that the shipping out-of-the-box configuration of the Kubernetes component that supports SMA is actually not vulnerable; that is the kubectl command is not run in such a way to cause the vulnerability out-of-box. However, because customers may run custom commands with the affected kubectl after the product is installed and deployed, Micro Focus has issued this security bulletin for customers to take action.
