S3CFG Configuration - File Exposure

What is the "S3CFG Configuration - File Exposure" module?

The "S3CFG Configuration - File Exposure" module is designed to detect a misconfiguration in the S3 storage service offered by Amazon. It focuses on the .s3cfg file and checks for the presence of sensitive information such as access keys, bucket location, and secret keys. This module is created to identify potential security risks and vulnerabilities related to the S3 storage configuration.

This module has an informative severity level, which means it provides valuable information about the potential exposure of sensitive data but does not directly indicate a vulnerability or exploit.

Impact

If the module detects a misconfigured .s3cfg file, it indicates that sensitive information related to the S3 storage service is exposed. This can potentially lead to unauthorized access, data breaches, and other security incidents. It is crucial to address any identified misconfigurations promptly to ensure the security and integrity of the S3 storage environment.

How does the module work?

The module works by sending an HTTP GET request to the "/.s3cfg" path. It then applies a series of matching conditions to determine if a misconfiguration is present. The matching conditions include:

- Checking for the presence of specific words such as "access_key," "bucket_location," and "secret_key" in the response body. - Verifying that the response header contains the word "text/plain". - Ensuring that the HTTP response status is 200 (OK).

If all the matching conditions are met, the module identifies a potential misconfiguration in the S3 storage service.

It is 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 various security issues.
