Pubspec YAML Configuration File Exposure

What is the "Pubspec YAML Configuration File Exposure?"

The "Pubspec YAML Configuration File Exposure" module is designed to detect misconfigurations in the pubspec.yaml file of a software project. The pubspec.yaml file is used in Dart and Flutter projects to define dependencies, versions, and other project metadata. This module specifically targets the exposure of the pubspec.yaml file, which can potentially reveal sensitive information about the project's configuration.

This module has a low severity level, indicating that the vulnerability it detects may have limited impact or pose a lower risk to the security of the software.

Impact

If the pubspec.yaml file is exposed, it can potentially expose sensitive information about the project's dependencies, versions, and environment configuration. This information can be leveraged by attackers to gain insights into the project's technology stack, identify potential vulnerabilities, or exploit misconfigurations.

How the module works?

The "Pubspec YAML Configuration File Exposure" module works by sending HTTP requests to specific paths where the pubspec.yaml file may be exposed, such as "/pubspec.yaml" or "/assets/pubspec.yaml". It then applies matching conditions to determine if the file is exposed and contains specific keywords, such as "version:", "environment:", and "dependencies:". The module also verifies that the HTTP response status is 200, indicating a successful request.

By detecting the presence of the pubspec.yaml file and specific keywords within it, the module identifies potential misconfigurations that may expose sensitive information. It reports these vulnerabilities to enable remediation and enhance the security of the software project.
