Appspec Yml Disclosure

What is the "Appspec Yml Disclosure?"

The "Appspec Yml Disclosure" module is designed to detect misconfigurations in the appspec.yml or appspec.yaml files. These files are commonly used in software deployment processes, specifically with AWS CodeDeploy. The module focuses on identifying potential exposure and configuration issues that could lead to security vulnerabilities.

This module has a medium severity level, indicating that while it may not pose an immediate threat, it should still be addressed to ensure the security of the deployment process.

Impact

If misconfigurations are present in the appspec.yml or appspec.yaml files, it could lead to various security risks. Attackers may be able to exploit these vulnerabilities to gain unauthorized access, manipulate the deployment process, or compromise the integrity of the deployed software.

How does the module work?

The "Appspec Yml Disclosure" module works by sending HTTP requests to the target application, specifically targeting the appspec.yml and appspec.yaml files. It then applies matching conditions to determine if any misconfigurations are present.

One example of a matching condition is checking for specific keywords in the body of the response, such as "version:", "os:", and "files:". Additionally, the module verifies that the HTTP response status is 200, indicating a successful request.

By combining these matching conditions, the module can identify potential misconfigurations in the appspec.yml or appspec.yaml files.
