Woodpecker CI Panel Detection Scanner

Woodpecker CI, a community fork of Drone CI, is used to provide a powerful yet simple continuous integration platform. It is a tool commonly utilized by development teams to automate the integration of code changes from multiple contributors into a central repository. Woodpecker CI facilitates the building, testing, and deployment of applications in various environments across different industries. Its platform is appreciated for being user-friendly and adaptable to a wide range of development workflows. Organizations leverage this tool to ensure that their software development processes are streamlined and efficient. It is an important component in modern DevOps pipelines, providing feedback to developers on their code quality.

The detection involves identifying the presence of a Woodpecker CI panel on a web server, which might be left exposed on the Internet. Typically, exposure of such panels can lead to unauthorized access, thereby compromising the CI environment. Woodpecker CI panels, if not properly secured, can lead to potential information disclosure or control over the CI processes. The detection aims to ensure that deployment of this continuous integration tool is compliant with security standards. Unauthorized individuals gaining access to such panels could modify CI configurations or inject malicious code into software builds.

Technical details include searching for characteristic indicators within the web page's HTML body, such as a specific title tag and web configuration file paths. The HTTP GET method is employed to fetch web resources, and responses are analyzed for certain patterns. The primary indicators include the presence of the "" tag and the existence of "/web-config.js" in the HTML body. A status code of 200 confirms the suspected pattern matches, indicating the presence of the Woodpecker CI panel.

If exploited by malicious actors, exposed Woodpecker CI panels could lead to unauthorized access to the CI/CD (Continuous Integration/Continuous Deployment) system. This might result in the leakage of sensitive credentials, configuration details leakage, or the ability to alter CI/CD pipelines. The potential impact also includes deployment of unwanted or harmful software into production environments. Furthermore, attackers could leverage this access to pivot to other parts of the network, using it as an initial point of intrusion.
