GolangCI-Lint Configuration File Exposure

What is the "GolangCI-Lint Configuration File Exposure?"

The "GolangCI-Lint Configuration File Exposure" module is designed to detect misconfigurations in the GolangCI-Lint configuration files. GolangCI-Lint is a popular static analysis tool for Go programming language code. This module focuses on identifying potential exposure of sensitive information in the configuration files, which could lead to security vulnerabilities.

This module has a low severity level, indicating that the impact of the exposure is relatively limited. However, it is still important to address any misconfigurations to ensure the security of the GolangCI-Lint setup.

This module was authored by Hardik-Solanki.

Impact

If the GolangCI-Lint configuration files are exposed, it could potentially reveal sensitive information about the project's linting rules and settings. This information could be leveraged by attackers to gain insights into the project's code quality practices and potentially identify weaknesses or vulnerabilities.

How the module works?

The module works by sending HTTP requests to specific paths commonly used for GolangCI-Lint configuration files, such as "/.golangci.yml" and "/.golangci.toml". It then applies matching conditions to determine if the exposed file contains specific keywords related to linting rules and settings, such as "linters:" and "linters-settings:".

An example of an HTTP request sent by this module:

GET /.golangci.yml

The matching conditions used by this module include checking the response status code, which should be 200 (indicating a successful response), and verifying the presence of the specified keywords in the response body.

If the module detects a match, it will report the vulnerability, indicating that the GolangCI-Lint configuration file is exposed and potentially at risk.
