OpenNMS Dashboard Exposure Detection Scanner

OpenNMS is an enterprise-grade network monitoring platform used by organizations to manage and monitor network performance and availability. It is commonly deployed within IT environments to provide visibility into network operations and infrastructure. OpenNMS is typically used by network administrators and IT professionals to detect, remedy, and prevent network issues. Organizations rely on this platform to ensure that their networks run smoothly and efficiently. It is particularly valued for its scalability and ability to handle large network environments. The software is widely adopted in sectors where network downtime can have significant impacts on business operations.

The vulnerability detected by this scanner relates to the exposure of the OpenNMS Dashboard. When left exposed, this dashboard can provide unauthorized users with access to sensitive network information. This vulnerability can be exploited to obtain insights into the monitored network, which can lead to privacy violations and data leakage. The exposure occurs due to misconfigurations that fail to secure access to the dashboard adequately. As a result, network infrastructure, alarms, and monitoring data may be visible to users without proper authorization. Mitigating this vulnerability is crucial to protect sensitive network data from potential threat actors.

Technically, the vulnerability arises from missing or inadequate access controls on the OpenNMS Dashboard. The endpoints vulnerable include paths like `{{BaseURL}}/opennms/index.jsp`, `{{BaseURL}}/opennms/dashboard.jsp`, and `{{BaseURL}}/opennms/`. These endpoints, when not properly secured, can be accessed by unauthorized users if certain keywords such as "OpenNMS Web Console" and "Dashboard" are present in the body of the HTTP response. A successful match occurs when there is an unauthorized status access with HTTP status 200. Exploiting this vulnerability can potentially lead to unauthorized data access and system manipulation.

The possible effects of this vulnerability being exploited include unauthorized access to network infrastructure details and monitoring data. Malicious users could utilize this information to further compromise network systems or exploit other vulnerabilities. The exposure could also contribute to a broader attack surface, facilitating additional unauthorized actions such as data exfiltration or system disruptions. Organizations may face reputational damage, regulatory penalties, and loss of customer trust as consequences of such security lapses. Addressing these exposures is critical to maintaining the confidentiality and integrity of organizational networks.
