CVE-2024-51228
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary operating system commands on affected TOTOLINK routers via the /boafrm/formSysCmd component. It affects multiple TOTOLINK router models running specific vulnerable firmware versions. Attackers can gain full control of the device without authentication.
💻 Affected Systems
- TOTOLINK-CX-A3002RU
- TOTOLINK-CX-N150RT
- TOTOLINK-CX-N300RT
- TOTOLINK-CX-N302RE
⚠️ 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
Complete device compromise allowing attackers to install persistent malware, pivot to internal networks, intercept traffic, or use the device as part of a botnet.
Likely Case
Attackers execute commands to modify device configuration, steal credentials, or use the router for DDoS attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to the router itself without lateral movement.
🎯 Exploit Status
The GitHub reference contains proof-of-concept code. Exploitation requires sending a crafted HTTP POST request to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official advisory found
Restart Required: Yes
Instructions:
1. Check TOTOLINK support pages for firmware updates
2. Download appropriate firmware for your model
3. Access router admin interface
4. Navigate to firmware upgrade section
5. Upload and apply new firmware
6. Reboot router
🔧 Temporary Workarounds
Disable remote administration
allPrevent external access to router web interface
Access router admin > Advanced Settings > Remote Management > Disable
Block access to vulnerable endpoint
linuxUse firewall rules to block /boafrm/formSysCmd
iptables -A INPUT -p tcp --dport 80 -m string --string "/boafrm/formSysCmd" --algo bm -j DROP
🧯 If You Can't Patch
- Isolate affected routers in separate VLAN with strict firewall rules
- Implement network monitoring for suspicious HTTP POST requests to /boafrm/formSysCmd
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via admin interface or attempt to access http://[router-ip]/boafrm/formSysCmdCheck Version:
curl -s http://[router-ip]/version.cgi || check router admin interfaceVerify Fix Applied:
Verify firmware version is updated beyond vulnerable versions listed above📡 Detection & Monitoring
Log Indicators:
- HTTP POST requests to /boafrm/formSysCmd
- Unusual command execution in system logs
- Failed authentication attempts to router admin
Network Indicators:
- HTTP traffic to router IP on port 80 with POST to vulnerable endpoint
- Outbound connections from router to suspicious IPs
