CVE-2024-32310
📋 TL;DR
This CVE describes a stack overflow vulnerability in Tenda F1203 routers that allows attackers to execute arbitrary code by sending specially crafted requests to the fromWizardHandle function. The vulnerability affects users running vulnerable firmware versions on these routers. Successful exploitation could lead to complete device compromise.
💻 Affected Systems
- Tenda F1203
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to full router compromise, credential theft, network traffic interception, and lateral movement into connected networks.
Likely Case
Router compromise allowing attackers to modify DNS settings, intercept traffic, or use the device as a pivot point for further attacks.
If Mitigated
Limited impact if device is behind firewall with restricted WAN access and proper network segmentation.
🎯 Exploit Status
Public GitHub repository contains vulnerability details and likely exploit code. Stack overflow vulnerabilities in embedded devices are frequently weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: Yes
Instructions:

3. Access router admin interface
4. Navigate to firmware upgrade section
5. Upload and apply new firmware
6. Reboot router
🔧 Temporary Workarounds
Disable WAN Management
allPrevent external access to router management interface
Network Segmentation
allIsolate router management interface to trusted network segment
🧯 If You Can't Patch
- Replace vulnerable device with supported model
- Implement strict firewall rules blocking all WAN access to router management ports
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router admin interface under System Status or Firmware Upgrade sectionCheck Version:
curl -s http://router-ip/goform/getStatus | grep versionVerify Fix Applied:
Verify firmware version has been updated to a version later than V2.0.1.6📡 Detection & Monitoring
Log Indicators:
