Technical details
The vulnerability is an execution with unnecessary privileges issue affecting Dell SCG 5.0 versions prior to 5.36.00.16 (appliance) and 5.36.00.00 (application). The root cause is an exposed Docker socket that allows a low-privileged operator with SSH access or a compromised service running in a container to escape container boundaries and gain host-level root access without authentication. Attack requires local access (either SSH access to the host or code execution within a container). An attacker can leverage the socket to execute arbitrary commands with root privileges. Patches are available in versions 5.36.00.16 and later.
