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?
registry/v2/_catalog
Container Registry Catalog
What an attacker could do
The Docker Registry v2 catalog lists every repository name on the registry, enabling an attacker to enumerate and pull all stored images, and on an unauthenticated registry to push malicious replacements.
How to defend it
Require token authentication on the registry, disable or restrict the _catalog endpoint, and serve only over TLS behind an authenticating proxy.
