You can detect Springboot Actuators using this tool.
Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". Actuator is mainly used to expose operational information about the running application — health, metrics, info, dump, env, etc. It uses HTTP endpoints or JMX beans to enable us to interact with it.
An attacker might use the disclosed information to harvest specific security vulnerabilities for the application identified.
Only use components that do not have known vulnerabilities, only use components that when combined to not introduce a security vulnerability, and ensure that a misconfiguration does not cause any vulnerabilities.
