CVE-2026-25069 is a path traversal vulnerability classified under CWE-22 affecting SunFounder Pironman Dashboard (pm_dashboard) versions 1.3.13 and prior. The vulnerability exists in the log file API endpoints where the filename parameter is not properly sanitized or restricted, allowing an attacker to supply directory traversal sequences (e.g., ../) to access files outside the intended directory. This flaw enables an unauthenticated remote attacker to read arbitrary files, potentially exposing sensitive configuration, credential, or system files. Furthermore, the attacker can delete arbitrary files, including critical system files, leading to data loss, system instability, or denial of service. The vulnerability does not require authentication or user interaction, making it highly exploitable remotely. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality (C:H), integrity (I:H), and availability (A:H). Although no known exploits have been reported in the wild yet, the critical severity and ease of exploitation make this a significant threat. The lack of available patches at the time of disclosure necessitates immediate risk mitigation by affected organizations.

For European organizations, exploitation of CVE-2026-25069 could result in severe consequences including unauthorized disclosure of sensitive data, deletion of critical files, and potential full system compromise or denial of service. Organizations relying on SunFounder Pironman Dashboard for industrial automation, IoT device management, or educational purposes may face operational disruptions and data breaches. The ability to delete arbitrary files could lead to loss of system integrity and availability, impacting business continuity. Confidential information exposure could also lead to regulatory compliance violations under GDPR, resulting in legal and financial penalties. The unauthenticated nature of the vulnerability increases the risk of widespread exploitation, especially in environments where the dashboard is exposed to untrusted networks or the internet. The threat is particularly acute for sectors with critical infrastructure or sensitive data managed via this software.

Immediate mitigation steps include restricting network access to the Pironman Dashboard API endpoints by implementing firewall rules or network segmentation to limit exposure to trusted internal networks only. Organizations should monitor and log access to the affected API endpoints to detect suspicious requests containing traversal sequences. Employing web application firewalls (WAFs) with custom rules to block path traversal patterns in the filename parameter can provide a temporary protective layer. Until an official patch is released, consider disabling or restricting the log file API functionality if feasible. Conduct thorough audits of system files and logs to identify any signs of exploitation or unauthorized file deletions. Additionally, implement strict file system permissions to limit the dashboard process's ability to delete or read sensitive files outside its intended directories. Regular backups of critical data and system files are essential to enable recovery in case of data loss. Finally, maintain close communication with SunFounder for patch releases and apply updates promptly once available.
