CVE-2020-15157: Insufficiently Protected Credentials

October 16, 2020 (updated November 18, 2021)

Containerd (an industry-standard container runtime) suffers from a credential leaking vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the default containerd resolver will follow that URL to attempt to download it. The default containerd resolver will provide its authentication credentials if the server where the URL is located presents an HTTP status code along with registry-specific HTTP headers. If an attacker publishes a public image with a manifest that directs one of the layers to be fetched from a web server they control, and they trick a user or system into pulling the image, they could obtain the credentials used for pulling that image. In some cases, this may be the user’s username and password for the registry. In other cases, this may be the credentials attached to the cloud virtual instance which can grant access to other cloud resources in the account. The default containerd resolver is used by the cri-containerd plugin (which can be used by Kubernetes), the ctr development tool, and other client programs that have explicitly linked against it. Other container runtimes built on top of containerd but not using the default resolver (such as Docker) are not affected.
