Spring Eureka Exposure

What is the "Spring Eureka Exposure?"

The "Spring Eureka Exposure" module is designed to detect potential misconfigurations in Spring Boot applications that use the Eureka service registry. Eureka is a client-side service discovery framework that allows applications to locate and communicate with each other. This module focuses on identifying instances where the Eureka dashboard or sensitive information related to Eureka is exposed, which could potentially lead to unauthorized access or information leakage.

This module has a low severity level, indicating that the identified issues may not pose an immediate threat but should still be addressed to ensure the security and integrity of the application.

Impact

If the "Spring Eureka Exposure" module detects a misconfiguration, it could potentially expose sensitive information related to the Eureka service registry. This could include details about registered services, endpoints, or other configuration parameters. Attackers could leverage this information to gain unauthorized access, perform reconnaissance, or launch further attacks against the application or its dependencies.

How does the module work?

The "Spring Eureka Exposure" module works by sending HTTP requests to the target application and analyzing the responses based on predefined matching conditions. It checks for specific content in the response body, such as the presence of the word "Eureka," the phrase "Toggle navigation," or "Last 1000 since startup." Additionally, it verifies that the HTTP response status is 200 (OK).

By combining these matching conditions, the module can identify instances where the Eureka dashboard or related information is exposed. It does not provide the exact JSON definitions or templates used for the HTTP requests, but it focuses on the technical aspects of the detection process.

For example, the module might send an HTTP request to the target application and expect a response with a status code of 200 and the word "Eureka" in the body. If these conditions are met, the module will flag the potential exposure.

It's important to note that this module is just one test case within the Vidoc platform, which utilizes multiple modules to perform comprehensive scanning and detection of vulnerabilities, misconfigurations, and software fingerprints.
