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?
envoy/admin/clusters
Envoy Proxy Admin Interface
What an attacker could do
The Envoy admin interface discloses upstream cluster endpoints and health, and exposes endpoints to drain listeners, change log levels, or dump configs and the heap, enabling reconnaissance and denial of service.
How to defend it
Bind the Envoy admin listener to 127.0.0.1 only, never expose it via a route or ingress, and restrict it with network policies.
