Detects Springboot HTTP Exchanges Actuator Exposure Detection Scanner
This scanner detects the use of Detects Springboot HTTP Exchanges Actuator Exposure in digital assets. The exposed HTTP exchange endpoint can leak recent HTTP request/response data, including URIs, headers, and status codes. Detecting such exposure can help in securing sensitive information shared in HTTP communications.

Spring Boot is a popular framework used for building stand-alone, production-grade Spring-based applications. It is utilized by developers to quickly set up and run applications with minimal configuration. Large enterprises, startups, and many organizations worldwide employ Spring Boot for its simplicity and powerful features. The framework supports a wide variety of deployment scenarios, including web applications and microservices architectures. Spring Boot is known for its embedded server options, dependency management, and its robust Actuator module for monitoring and management. Being open-source and backed by Pivotal, it is continuously evolving with community and commercial support.
The vulnerability detected by this scanner relates to the exposure of the HTTP exchanges endpoint in the Spring Boot's Actuator module. This endpoint can leak detailed information about recent HTTP requests and responses handled by the server. Exposing such data publicly can lead to unauthorized information disclosure. Malicious actors can leverage this exposed data to gather insights about the request patterns and potentially sensitive data like headers and URIs. The vulnerability can pose a significant risk especially if the data includes authentication headers or sensitive query parameters.
In terms of technical details, the vulnerability involves the exposure of the '/httpexchanges' endpoint in the Spring Boot Actuator. When exposed, this endpoint can be accessed without authentication, revealing details about HTTP requests and responses. The scanner checks for responses from this endpoint that contain data tags like "exchanges," "request," and "response" in the body. It also looks for specific content types in the headers, such as 'application/json' and 'application/vnd.spring-boot.actuator.v3+json', indicating an exposed actuator endpoint. The endpoint typically returns HTTP status code 200 upon exposure.
Exploit of this vulnerability by threat actors may result in the exposure of sensitive internal data, unauthorized insights into API usage, and potential targeting of other vulnerabilities if authentication data or API keys are disclosed. Such leaks can collectively lead to a broader attack surface and potential exploitation of other weak points in the application's security. Additionally, these leaks may aid in planning further attacks, such as session hijacking or crafting phishing attempts with gathered sensitive data.
