CVE-2025-41705
📋 TL;DR
CVE-2025-41705 allows an unauthenticated attacker positioned as a man-in-the-middle (MITM) to intercept websocket communications and capture login credentials for the Webfrontend. This affects systems using vulnerable websocket implementations without proper encryption or authentication. Organizations using affected products with exposed web interfaces are at risk.
💻 Affected Systems
- Specific product information not provided in references
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the system, leading to complete compromise, data theft, and potential lateral movement within the network.
Likely Case
Attackers capture valid credentials and gain unauthorized access to the web interface, potentially modifying configurations or accessing sensitive data.
If Mitigated
With proper network segmentation and monitoring, impact is limited to credential exposure requiring password resets.
🎯 Exploit Status
Requires MITM position; no public exploit code known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor-specific updates
Vendor Advisory: https://certvde.com/de/advisories/VDE-2025-072
Restart Required: No
Instructions:
1. Check vendor advisory for specific patch information. 2. Apply vendor-provided security updates. 3. Verify websocket implementation uses proper encryption (WSS).
🔧 Temporary Workarounds
Enforce HTTPS/WSS Only
allConfigure web servers to only accept HTTPS and WSS connections, preventing unencrypted websocket traffic.
# Configure web server to redirect HTTP to HTTPS
# Set HSTS headers
# Disable plain websocket (WS) protocol
Network Segmentation
allIsolate vulnerable systems from untrusted networks to reduce MITM attack surface.
# Implement firewall rules to restrict access
# Use VLAN segmentation
# Deploy in protected network zones
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the vulnerable interface
- Deploy certificate pinning or mutual TLS authentication for websocket connections
🔍 How to Verify
Check if Vulnerable:
Test if websocket connections are using unencrypted WS protocol instead of encrypted WSS
Check Version:
Check application version against vendor's patched version list
Verify Fix Applied:
Verify all websocket connections use WSS (wss://) and test for MITM resistance
📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from new locations
- Unusual websocket connection patterns
- Authentication logs showing access from unexpected IPs
Network Indicators:
- Unencrypted websocket traffic (WS protocol)
- MITM attack patterns in network traffic
- Suspicious ARP or DNS poisoning attempts
