CVE-2025-25265
📋 TL;DR
This vulnerability allows authenticated high-privileged remote attackers to read arbitrary files from the controller's file system through a web application configuration endpoint. It affects systems running the vulnerable controller configuration web application. Attackers must have administrative credentials to exploit this flaw.
💻 Affected Systems
- Controller configuration web application
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Sensitive configuration files, credentials, or system files could be exfiltrated, potentially leading to full system compromise through credential reuse or further exploitation.
Likely Case
Attackers with administrative access could read configuration files containing sensitive information, potentially enabling lateral movement or privilege escalation.
If Mitigated
With proper access controls and network segmentation, impact is limited to file disclosure within the controller's accessible file system.
🎯 Exploit Status
Exploitation requires administrative credentials but is straightforward once authenticated
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://certvde.com/en/advisories/VDE-2025-018/
Restart Required: No
Instructions:
1. Monitor vendor for patch release
2. Apply patch when available
3. Verify fix by testing file read functionality
🔧 Temporary Workarounds
Restrict network access
allLimit access to the controller configuration web application to trusted networks only
Configure firewall rules to restrict access to controller web interface
Implement authentication hardening
allStrengthen authentication mechanisms and monitor for suspicious admin account activity
Enable MFA if supported
Implement strong password policies
Monitor authentication logs
🧯 If You Can't Patch
- Implement network segmentation to isolate controller from untrusted networks
- Monitor file access logs for unusual read patterns from the web application
🔍 How to Verify
Check if Vulnerable:
Test if authenticated admin users can access file read functionality at the vulnerable endpointCheck Version:
Check web application version through admin interface or configuration filesVerify Fix Applied:
Verify file read functionality is properly restricted after remediation📡 Detection & Monitoring
Log Indicators:
- Unusual file read requests from web application
- Multiple failed authentication attempts followed by successful admin login
Network Indicators:
- Unusual outbound traffic from controller containing file data
- Requests to file read endpoints from unexpected sources
