According to its self-reported version, Cisco IOS-XE Software is affected by a vulnerability in the on-device application development workflow feature for the Cisco IOx application hosting infrastructure that could allow an authenticated, remote attacker to access the underlying operating system as the root user. This vulnerability exists because Docker containers with the privileged runtime option are not blocked when they are in application development mode. An attacker could exploit this vulnerability by using the Docker CLI to access an affected device. The application development workflow is meant to be used only on development systems and not in production systems.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
