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?
consul/v1/agent/self
HashiCorp Consul Agent Info
What an attacker could do
The agent-self endpoint discloses Consul version, datacenter, node name, and configuration, and an open HTTP API lets an attacker read service registrations, KV secrets, and register malicious services.
How to defend it
Enable ACLs with a default-deny policy and TLS, bind the HTTP API to localhost or a private network, and require tokens for all API access.
