Description
On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.
