Name of the Vulnerable Software and Affected Versions Crux Linux Docker images versions 3.0 through 3.4

Description The official Crux Linux Docker images contain a blank password for a root user. Systems using the Crux Linux Docker container deployed by affected versions of the Docker image may allow an attacker to achieve root access with a blank password.

Recommendations For versions 3.0 through 3.4, update the Docker image to a version that does not contain a blank password for the root user. As a temporary workaround, consider changing the root password to a secure value until a patched version of the Docker image is available. Restrict access to the Docker container to minimize the risk of exploitation.
