CVE-2025-2728
📋 TL;DR
This critical vulnerability in H3C Magic NX30 Pro and Magic NX400 routers allows authenticated attackers on the local network to execute arbitrary commands via command injection in the /api/wizard/getNetworkConf endpoint. Successful exploitation could lead to complete device compromise. Only users of affected H3C router models with vulnerable firmware versions are impacted.

⚠️ Risk & Real-World Impact
Worst Case
Full router compromise allowing attacker to intercept all network traffic, install persistent backdoors, pivot to other internal systems, and potentially disrupt network connectivity.
Likely Case
Attacker gains administrative control of the router, enabling traffic monitoring, credential theft, and network reconnaissance from within the local network.
If Mitigated
With proper network segmentation and access controls, impact is limited to the router itself without lateral movement to other critical systems.
🎯 Exploit Status
Exploitation requires understanding of the API endpoint and command injection techniques, but is feasible for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after V100R014
Vendor Advisory: https://www.h3c.com/cn/Service/Document_Software/Software_Download/Consume_product/
Restart Required: No
Instructions:
1. Access H3C official download portal. 2. Download firmware version newer than V100R014. 3. Upload firmware via router web interface. 4. Apply update without restarting services.
🔧 Temporary Workarounds
Network Segmentation
allIsolate affected routers in separate VLANs to limit attack surface
Access Control Lists
allRestrict access to router management interfaces to trusted IP addresses only
🧯 If You Can't Patch
- Segment affected routers from critical internal networks using VLANs or firewalls
- Implement strict network monitoring for unusual API calls to /api/wizard/getNetworkConf
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface or SSH. If version is V100R014 or earlier, device is vulnerable.Check Version:
ssh admin@router-ip 'show version' or check web interface System Information pageVerify Fix Applied:
Verify firmware version is newer than V100R014 and test that /api/wizard/getNetworkConf endpoint properly sanitizes input.📡 Detection & Monitoring
Log Indicators:
- Unusual API calls to /api/wizard/getNetworkConf
- Command execution patterns in system logs
- Multiple failed authentication attempts followed by successful API access
Network Indicators:
- Unusual outbound connections from router to external IPs
- Traffic patterns suggesting router compromise
SIEM Query:
