Grafana vs Kibana: What Public Internet Logs Reveal

Grafana and Kibana dashboards that are accidentally left exposed on the public internet reveal a startling amount of sensitive operational data—including internal IP addresses, database names, error logs with stack traces, and sometimes even credentials or customer information. By analyzing these exposed dashboards, security researchers and curious users can map internal network structures, identify specific software versions, and understand the real-world deployment patterns of thousands of organizations. This article explains what these public dashboards actually show, why they get exposed, and what you can learn from them.

What Exposed Grafana and Kibana Dashboards Typically Show

When a Grafana or Kibana instance is left accessible without authentication, anyone can view the dashboards that the organization built for its own monitoring. These dashboards are not generic—they are tailored to the specific infrastructure. Common data points include:

• Internal IP addresses and hostnames of servers, databases, and application nodes
• Application performance metrics like request latency, error rates, and CPU/memory usage
• Log messages containing stack traces, SQL queries, and sometimes user IDs or email addresses
• Infrastructure details such as Kubernetes cluster names, pod names, and cloud provider regions
• Custom dashboards that reveal business logic, feature usage, and internal naming conventions

For example, a publicly exposed Kibana dashboard for an e-commerce site might show real-time order processing times, database query logs with table names, and internal service endpoints. A Grafana dashboard for a SaaS company might display active user counts, API key usage, and server fleet status.

How These Dashboards Get Exposed

The root cause is almost always misconfiguration. Developers or administrators deploy Grafana or Kibana for internal monitoring, then accidentally bind the service to 0.0.0.0 (all interfaces) instead of localhost, or place it in a public subnet without a firewall rule. Often they intend to share dashboards with colleagues or clients and forget to enable authentication afterward. Default installations of both tools require some setup to enable login, and many users skip that step in testing or small deployments.

Another common path is through reverse proxies. A team sets up an nginx or Apache proxy to serve Grafana or Kibana on a subdomain, but forgets to add basic auth or IP whitelisting. Search engines like Shodan and Censys continuously scan the internet for these services, indexing them by their default ports (3000 for Grafana, 5601 for Kibana) and HTTP banners.

What Public Dashboards Reveal About the Organization

Beyond the obvious technical details, exposed dashboards paint a detailed picture of an organization’s operations. They reveal:

• Tech stack – which databases, message queues, and cloud services are in use
• Scale – number of servers, requests per second, and data volumes
• Business rhythms – peak usage times, batch job schedules, and maintenance windows
• Security posture – whether they monitor for anomalies, how quickly they respond to errors, and which alerts they consider important
• Internal naming conventions – useful for social engineering or further targeted attacks

For security researchers, this is a goldmine. A dashboard showing a database error with a full SQL query might reveal table names and schema. A log entry with a stack trace can expose internal library versions, which can then be checked against known vulnerabilities. Even without credentials, an attacker can use this information to craft more convincing phishing emails or to identify high-value targets within the network.

How to Detect and Protect Against Exposure

If you run Grafana or Kibana, you should regularly check whether your instance is publicly accessible. Here are practical steps:

1. Scan your own IP – use a tool like Nmap or an online port checker to see if ports 3000 or 5601 respond from outside your network.
2. Check reverse proxy configs – ensure that any subdomain serving these tools has authentication enabled and is not accidentally exposed.
3. Enable authentication – configure Grafana’s auth.anonymous to false and Kibana’s xpack.security.enabled to true.
4. Restrict network access – use firewall rules or security groups to allow only specific IP ranges.
5. Use a VPN or SSO – require users to connect through a virtual private network or a single sign-on provider.
6. Monitor for unknown access – check access logs for requests from unfamiliar IPs, especially those from cloud providers or VPN services.

Regularly reviewing your own external attack surface is the best defense. Tools like Shodan can even alert you when a new open port is detected on your IP range.

Grafana vs Kibana: Which Is More Commonly Exposed?

Both tools appear in public exposure scans, but they serve different purposes. Grafana is primarily a metrics visualization tool, often paired with Prometheus or InfluxDB. Kibana is the visualization layer for Elasticsearch, used for log analysis and full-text search. In practice, Kibana dashboards tend to expose more sensitive log data because logs often contain raw application output, while Grafana dashboards focus on aggregated metrics that are less granular.

However, Grafana is sometimes configured with data source credentials stored in its configuration file. If an attacker gains access to the Grafana UI, they may be able to query the underlying data sources directly, potentially extracting more detailed information than what is shown on the dashboards. Kibana, on the other hand, typically requires separate authentication to access the underlying Elasticsearch data, so an exposed Kibana instance may only reveal what is indexed in the current index pattern.

Real-World Examples of Exposure

Security researchers have documented numerous cases of exposed dashboards. For instance, a major cryptocurrency exchange had a Grafana instance publicly accessible that showed internal trading volumes and server health. A healthcare startup left a Kibana dashboard open that displayed patient appointment logs with names and email addresses. A government agency in Europe had a Grafana instance exposing internal network topology and firewall rules.

These are not isolated incidents. Shodan searches for “Grafana” and “Kibana” regularly return thousands of results worldwide. The exposure is often unintentional, but the consequences can be severe—ranging from data breaches to targeted attacks on internal systems.

Frequently Asked Questions

Can exposed dashboards be used to hack into a system?

Yes, indirectly. While the dashboard itself may not allow direct code execution, the information it reveals—internal IPs, software versions, database names, and error details—can be used to craft targeted attacks. For example, knowing that a server runs a specific version of Elasticsearch with a known vulnerability could lead to a successful exploit.

Is it illegal to view an exposed dashboard?

Viewing publicly accessible data is generally not illegal, but unauthorized access to a system—even if it is misconfigured—can be considered a crime in many jurisdictions. The line between “public” and “unauthorized” is blurry. It is safest to avoid interacting with exposed dashboards beyond a simple check, and never attempt to modify or extract data.

How can I tell if my own Grafana or Kibana is exposed?

Use an external port scanner like Shodan or a simple online port checker to see if port 3000 or 5601 is open from the internet. You can also try accessing your public IP with those ports in a browser. If you see a login page or dashboards, it is exposed.

What should I do if I find an exposed dashboard that isn’t mine?

You can report it to the organization via a responsible disclosure channel, such as a security contact email or a bug bounty program. Do not attempt to access or modify any data. Many organizations appreciate the heads-up and will fix the issue quickly.

Does using a reverse proxy make the dashboard secure?

Not automatically. A reverse proxy can add authentication or IP restrictions, but if it is misconfigured—for example, without any auth—it still exposes the dashboard. Always test the public endpoint after setting up a proxy.
