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?
v2/_catalog
Docker registry
What an attacker could do
An unauthenticated Docker Registry v2 catalog endpoint lists every repository, letting an attacker pull private images to extract embedded secrets, source code, and credentials, or push malicious images if writes are also open.
How to defend it
Require authentication and TLS on the registry, place it behind an authenticating proxy or token service, and never bind it to a public interface without access controls.
