CVE-2024-53945
📋 TL;DR
This vulnerability allows authenticated attackers to execute arbitrary operating system commands with root privileges on KuWFi 4G AC900 LTE routers. Attackers can achieve full system compromise by injecting shell metacharacters into HTTP API parameters. All users of the affected router version are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Complete router takeover enabling persistent remote access, network traffic interception, lateral movement to connected devices, and disabling of security controls.
Likely Case
Router compromise leading to unauthorized network access, credential theft, and installation of backdoors for persistent access.
If Mitigated
Limited impact if strong authentication controls prevent unauthorized access to the web interface.
🎯 Exploit Status
Exploitation requires authentication but is straightforward once authenticated. Public proof-of-concept exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Contact vendor for firmware updates and monitor their security advisories.
🔧 Temporary Workarounds
Disable HTTP API endpoints
allBlock or disable access to vulnerable endpoints /goform/formMultiApnSetting and /goform/atCmd if possible through router configuration.
Change default credentials
allEnsure strong, unique passwords are set for router administration to prevent unauthorized authentication.
🧯 If You Can't Patch
- Isolate affected routers in network segments with strict firewall rules limiting inbound/outbound traffic
- Implement network monitoring for suspicious HTTP requests to the vulnerable endpoints
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface. If version is 1.0.13, the device is vulnerable. Test authenticated requests to /goform/formMultiApnSetting or /goform/atCmd with shell metacharacters.Check Version:
Check via router web interface under System Status or Administration settingsVerify Fix Applied:
Verify firmware version has been updated beyond 1.0.13. Test that command injection attempts no longer succeed.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /goform/formMultiApnSetting or /goform/atCmd containing shell metacharacters like ;, |, &, $, (, )
Network Indicators:
- Unusual outbound connections from router, unexpected telnet/SSH services enabled
