circleci config.yml exposure

What is the "circleci config.yml exposure?"

The "circleci config.yml exposure" module is designed to detect misconfigurations in the CircleCI configuration file (config.yml). CircleCI is a continuous integration and delivery platform that allows developers to automate their software development processes. This module focuses on identifying potential vulnerabilities in the CircleCI configuration file, which could lead to unauthorized access or exposure of sensitive information. The severity of this module is classified as low, indicating that the impact of the detected misconfigurations may be limited.

Impact

If misconfigurations are present in the CircleCI configuration file, it could result in security vulnerabilities that may be exploited by malicious actors. This could potentially lead to unauthorized access to sensitive data, compromise of the CI/CD pipeline, or disruption of the software development process. It is important to address any identified misconfigurations to ensure the security and integrity of the CircleCI environment.

How the module works?

The "circleci config.yml exposure" module works by sending an HTTP GET request to the path "/.circleci/config.yml" and applying matching conditions to identify misconfigurations. The matching conditions include:

- Checking if the response body contains the string "version: " and "jobs:" using regular expressions. - Verifying that the HTTP response status is 200 (OK).

If both matching conditions are met, the module flags the CircleCI configuration file as potentially misconfigured. This allows users to take appropriate actions to address the identified issues and enhance the security of their CircleCI environment.
