Firebase Debug Log File Exposure

What is the "Firebase Debug Log File Exposure?"

The "Firebase Debug Log File Exposure" module is designed to detect a potential security vulnerability in Firebase applications. Firebase is a popular mobile and web application development platform provided by Google. This module specifically targets the exposure of debug log files in Firebase applications.

The severity of this vulnerability is classified as low, indicating that it may not pose an immediate threat but should still be addressed to prevent potential exploitation.

This module was authored by Hardik-Solanki.

Impact

If debug log files in a Firebase application are exposed, it can potentially leak sensitive information about the application's internal workings, including API keys, user data, and other confidential information. This can be exploited by malicious actors to gain unauthorized access or perform other malicious activities.

How the module works?

The "Firebase Debug Log File Exposure" module works by sending an HTTP GET request to the "/firebase-debug.log" path of the target application. It then applies matching conditions to determine if the debug log file is exposed.

The matching conditions for this module are as follows:

- The response body must contain the words "[debug]", "firebase", and "googleapis.com". - The HTTP response status code must be 200.

If both matching conditions are met, the module will report a vulnerability.

Here is an example of the HTTP request sent by the module:

GET /firebase-debug.log

Please note that this is a simplified example and the actual HTTP request may contain additional headers or parameters.

It is important to address any identified vulnerabilities related to the exposure of debug log files in Firebase applications to ensure the security and confidentiality of the application and its users.
