Cloud Config File Exposure

What is "Cloud Config File Exposure?"

The "Cloud Config File Exposure" module is designed to detect misconfigurations in cloud environments that may expose sensitive configuration files. It targets cloud-based systems and applications that utilize cloud configuration files. This module has a medium severity level.

Impact

If a cloud configuration file is exposed, it can potentially lead to unauthorized access and compromise of sensitive information. Attackers may gain access to credentials, API keys, or other sensitive data stored in these files, which can be used to further exploit the system or launch targeted attacks.

How the module works?

The "Cloud Config File Exposure" module works by sending HTTP requests to specific paths in the target system, such as "/cloud-config.yml" or "/core-cloud-config.yml". It then applies matching conditions to determine if the response contains certain keywords, such as "ssh_authorized_keys" or "#cloud-config". Additionally, it checks if the response status is 200 (OK).

Example HTTP request:

GET /cloud-config.yml

The module matches the response against the following conditions:

- The response must contain all the specified keywords ("ssh_authorized_keys" and "#cloud-config"). - The response status must be 200 (OK).

If both conditions are met, the module reports a vulnerability indicating that the cloud configuration file is exposed.
