CVE-2020-24263Network attack vector

Host code execution via unrestricted container capabilities

Published Mar 16, 2021 · Updated Aug 4, 2024

Incorrect permissions in Portainer 1.24.1 and earlier allow remote authenticated users to execute code on the Docker host. The container deployment controls accept user-supplied Linux capabilities from non-admin users through the UI, stacks, or API without blocking host-sensitive capabilities such as SYS_MODULE. A non-admin account able to deploy a container can load kernel modules from that container and take over the host.
