💻 Affected Systems
- Tenda AC10
📦 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 the router is behind a firewall with restricted WAN access and proper network segmentation.
🎯 Exploit Status
Exploitation requires access to the router's web interface. The vulnerability is well-documented in public repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: Yes
Instructions:
1. Check Tenda's official website for firmware updates. 2. Download the latest firmware for AC10. 3. Log into router admin panel. 4. Navigate to System Tools > Firmware Upgrade. 5. Upload and install the new firmware. 6. Reboot the router.
🔧 Temporary Workarounds
Disable WAN Management
allPrevent external access to the router's management interface
Change Default Credentials
allUse strong, unique passwords for router administration
🧯 If You Can't Patch
- Isolate the router on a separate VLAN with strict firewall rules
- Implement network monitoring for unusual traffic patterns from the router
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin panel under System Status or System ToolsCheck Version:
Log into router web interface and navigate to System Status pageVerify Fix Applied:
