Harbor Panel Detection Scanner

Harbor is an open-source container image registry project that helps users secure and manage container images across cloud native platforms such as Kubernetes and Docker. It is widely used by organizations of various sizes for hosting and distributing Docker container images. Harbor provides advanced features like user management, access control, activity auditing, and does not require users to adapt to proprietary forms of storage or have additional costs related to proprietary offerings. Businesses and developers use Harbor to maintain security and integrity in their container supply chain ecosystem. The development community surrounding Harbor continuously contributes to improving the software, keeping it reliable and feature-complete to fulfill user needs.

The vulnerability detected by the scanner involves identifying the presence of a Harbor login panel. Harbor panels usually host sensitive operations and provide access to underlying container images, configurations, and policies. Unauthorized access or incorrect configuration of this login panel can lead to potential risks like exposure of sensitive data. By detecting the presence of the Harbor login panel, this scanner helps administrators recognize areas where access control measures might be necessary. Security best practices incorporate strict monitoring and filtering of access attempts to prevent unintentional exposure. This information can be essential for tightening the security environments involved in container management systems.

The detection process involves checking HTTP response status codes and analyzing the response body for specific strings associated with Harbor, such as harbor orharbor-app>". The vulnerable endpoints inspected by the scanner are related to system information and sign-in paths that may reveal the existence of a Harbor instance. Appropriate matching conditions and patterns have been set to validate the presence of a legitimate Harbor panel, minimizing false positives. These endpoints are critical since they offer entry points into the Harbor dashboard, where administrative actions can be carried out. Proper identification enables IT security teams to evaluate and adjust access permissions accordingly.

Exploitation of this vulnerability can lead to significant security implications, including unauthorized access to the Harbor dashboard and subsequent exposure of credentials or sensitive system data. If malicious actors gain access to Harbor, they could alter container images, configurations, or audit logs, potentially compromising the entire container operation and service delivery. This could lead to data tampering, service disruption, or even denial of service. Furthermore, if access control is not adequately enforced, sensitive data like user credentials and configuration details could be intercepted or manipulated, leading to data breaches or other malicious activities.
