Gogs (Go Git Service) Web Installer Scanner

Gogs (Go Git Service) is a lightweight, Git service that is widely used by developers and organizations for source code hosting. It is designed to be easy to install and configure, supporting a self-hosted Git environment. Developers use Gogs for collaborating on coding projects and managing version control in private or public repositories. The service is preferred by small to medium-sized development teams due to its minimal system requirements and user-friendly interface. Gogs can be deployed on various operating systems including Linux, Windows, and macOS, and is popular in environments where control over infrastructure is desired. It is often chosen for its simplicity and the ability to integrate with external services for enhanced functionality.

The detected misconfiguration relates to the availability of the Gogs Web Installer. This vulnerability manifests when the installation page of Gogs is improperly secured and left accessible. It allows unauthorized users to potentially view or modify installation configurations, risking exposure of sensitive data or alteration of the Gogs environment. This vulnerability is a form of security misconfiguration, revealing sensitive settings that should be restricted post-installation. If exploited, it grants malicious individuals the opportunity to compromise the setup of the Gogs service. It is crucial to lock down installation interfaces immediately following initial setup to prevent unauthorized access.

Access to the Gogs Web Installer is facilitated over HTTP, typically signaled by specific status codes and unique endpoint characteristics in the application. The misconfiguration is commonly located at the '/install' endpoint, with configurations related to database and general settings. This open access can inadvertently expose the system to potential threats, including configuration tampering. Unauthorized entities leveraging this area can modify setup parameters, leading to improper file processing or data exposure. To detect this, a security assessment leverages HTTP GET requests while matching specific content indicators present only on the installation screen.

When exploited, this vulnerability can allow unauthorized users to intercept, manipulate, and control the setup process, potentially resulting in privilege escalation and unauthorized data access. Unauthorized access could lead to the modification of sensitive settings and configuration parameters within Gogs. This might culminate in a compromised service where integrity and confidentiality of data are at risk. The overall functionality and security posture of the deploying environment can suffer significant degradation.
