CVE-2026-25069 is a path traversal vulnerability classified under CWE-22 affecting SunFounder Pironman Dashboard (pm_dashboard) versions up to 1.3.13. The vulnerability exists in the log file API endpoints where the filename parameter is improperly sanitized, allowing an attacker to supply directory traversal sequences (e.g., '../') to access files outside the intended restricted directory. Because the API is accessible without authentication, a remote attacker can exploit this flaw to read sensitive files such as configuration files, credentials, or logs, and also delete arbitrary files on the system. This can lead to data leakage, destruction of critical files, denial of service, or even full system compromise if key system files are deleted or manipulated. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges or user interaction required (PR:N/UI:N), and high impact on confidentiality, integrity, and availability (VC:H/VI:H/VA:H). The vulnerability is severe due to the combination of ease of exploitation and potential for significant damage. No patches or exploit code are currently publicly available, but the risk remains high due to the nature of the flaw and the unauthenticated access.

For European organizations, especially those deploying SunFounder Pironman Dashboard in industrial control systems, IoT environments, or network management, this vulnerability poses a critical risk. Exploitation could lead to unauthorized disclosure of sensitive operational data, intellectual property, or personal data protected under GDPR. Deletion of critical files could disrupt business operations, cause downtime, or damage system integrity, potentially leading to safety hazards in industrial contexts. The unauthenticated nature of the vulnerability increases the attack surface, allowing remote attackers to exploit it without insider access. This could facilitate ransomware attacks, espionage, or sabotage. Organizations in sectors such as manufacturing, energy, and critical infrastructure in Europe could face operational, financial, and reputational damage if exploited.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include restricting network access to the pm_dashboard API endpoints via firewalls or network segmentation to trusted IPs only. Implement web application firewalls (WAFs) with custom rules to detect and block path traversal patterns in API requests. Conduct thorough monitoring and logging of access to the dashboard and file system for suspicious activity. Disable or restrict the log file API endpoints if possible until a patch is released. Apply the principle of least privilege to the service account running the dashboard to minimize the impact of file deletion. Regularly back up critical files and system configurations to enable recovery in case of deletion or corruption. Stay alert for vendor updates or patches and apply them promptly once available.
