CVE-2026-25069
📋 TL;DR
SunFounder Pironman Dashboard versions 1.3.13 and earlier contain an unauthenticated path traversal vulnerability in log file API endpoints. Attackers can use directory traversal sequences in filename parameters to read or delete arbitrary files on the system. This affects all deployments using vulnerable versions of the pm_dashboard software.
💻 Affected Systems
- SunFounder Pironman Dashboard (pm_dashboard)
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through reading sensitive files like /etc/shadow or SSH keys, followed by deletion of critical system files causing permanent data loss and system destruction.
Likely Case
Information disclosure of configuration files, logs, and credentials, with potential deletion of application files causing service disruption.
If Mitigated
Limited to reading non-sensitive application logs if proper file permissions and network segmentation are implemented.
🎯 Exploit Status
Simple HTTP requests with path traversal sequences (../) in filename parameter can trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider workarounds or alternative software.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to the dashboard service using firewall rules
sudo ufw deny from any to any port 5000
sudo iptables -A INPUT -p tcp --dport 5000 -j DROP
Application Firewall/Reverse Proxy
linuxDeploy a reverse proxy with request filtering to block path traversal sequences
# Configure nginx/apache to filter requests containing ../ or similar patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the dashboard from sensitive systems
- Run the service with minimal privileges using a dedicated user account with restricted file access
🔍 How to Verify
Check if Vulnerable:
Test by sending HTTP GET request to /api/logs?filename=../../../etc/passwd and checking for file content in response
Check Version:
Check the version in pm_dashboard.py or package metadata
Verify Fix Applied:
Verify that path traversal attempts return error responses instead of file contents
📡 Detection & Monitoring
Log Indicators:
- HTTP requests with ../ sequences in filename parameter
- Access to files outside expected log directory
Network Indicators:
- Unusual file read patterns from dashboard service
- HTTP requests to log endpoints with traversal sequences
SIEM Query:
source="pm_dashboard" AND (url="*../*" OR filename="*../*")
