SunFounder Pironman Dashboard Path Traversal Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-25069

The vulnerability exists in a dashboard application designed for monitoring Raspberry Pi hardware. While it exposes an API, such dashboards are typically deployed on local networks or for personal use rather than as public-facing internet services. Public internet reachability is possible depending on user configuration, but it is not the standard or intended deployment pattern.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory details a critical vulnerability in SunFounder Pironman Dashboard software that could allow unauthenticated attackers to read or delete arbitrary files on affected systems. The issue arises from improper handling of filenames in API endpoints, potentially leading to sensitive data disclosure, system compromise, or denial of service. The main concern at this time is confirming relevance and exposure due to the typical deployment of this software.

Unauthenticated access to read/delete system files.
Poses a risk of data loss and system compromise.
Confirm relevance and exposure to affected systems.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by accessing the dashboard's log file API endpoints over the network. By sending specially crafted requests with traversal sequences in the filename parameter, they can read or delete arbitrary files on the system. This could lead to the disclosure of sensitive information and the deletion of critical system files, potentially causing system compromise or denial of service.

No authentication required.
Traverse path using filename parameter.
Sensitive data exposure and denial of service.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to read or delete arbitrary files on a system running the Pironman Dashboard, when exposed. This could lead to the disclosure of sensitive information or critical system files.

Sensitive system and user files.
Via log file API endpoints.
Data loss and potential system compromise.

Operational Fix

Recommended remediation, mitigation, and detection steps

The SunFounder Pironman Dashboard, specifically its log file API endpoints, is vulnerable to path traversal, allowing unauthenticated attackers to read and delete arbitrary files. Given this is a dashboard application often used for local monitoring, the primary responsibility likely falls to the system or application owner who deployed and manages the Raspberry Pi device. The first practical step is to identify all instances of the Pironman Dashboard, assess their network exposure and business criticality, and then coordinate remediation with the accountable owner.

Identify system owners for Pironman Dashboard.
Verify network exposure and business impact.

Frequently asked questions

What is the SunFounder Pironman Dashboard?

The Pironman Dashboard is a software component designed for Raspberry Pi users to monitor and manage their device's hardware status. It typically provides a web-based interface for tracking metrics like temperature, fan speed, and system health. Because it interacts directly with the underlying hardware and operating system, it maintains administrative-level visibility over the local machine.

What does path traversal mean in CVE-2026-25069?

This vulnerability is classified as CWE-22, or Path Traversal. It occurs when software fails to properly sanitize input before using it to access files. In this specific case, an attacker can use special character sequences—like dots and slashes—in a file request to 'escape' the intended folder and access unauthorized locations on the system, allowing them to read sensitive files or delete critical system data.

How can an attacker trigger this vulnerability?

An attacker exploits this by sending crafted requests to the dashboard’s specific log file API endpoints. They inject traversal sequences into the 'filename' parameter to navigate outside the permitted directory. It is important to note that this requires network access to the API; requests that do not target the log file API endpoints or that lack these specific malicious path sequences do not trigger the vulnerability.

Is my device at risk based on Halo Surface Signal?

Halo Surface Signal notes that while this dashboard is primarily designed for local monitoring or personal use, the risk depends on your network configuration. If your device is configured to be internet-facing rather than restricted to a private, internal network, the potential for unauthorized remote access increases significantly. You should verify whether your specific deployment allows external traffic.

What should I do if I use this dashboard?

Your first step is to locate all instances of the Pironman Dashboard currently running within your environment. Once identified, evaluate whether these instances are accessible from the internet or restricted to your local network. You should then coordinate with the system owners to assess the criticality of the device and monitor for official updates to resolve the file handling flaw.
