Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
api/v1/containerd/containers
containerd Container Management
What an attacker could do
An exposed containerd API lets an attacker list, create, and exec into containers on the host, pulling arbitrary images and mounting host paths to break out to the underlying node.
How to defend it
Bind the containerd gRPC socket to a local Unix socket only, restrict its file permissions to root, and never expose the CRI endpoint over TCP or an ingress.
