CVE-2024-44563
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Tenda AX1806 routers via a stack overflow in the setIptvInfo function. Attackers can exploit this by sending specially crafted requests to the iptv.stb.port parameter. All users running the vulnerable firmware version are affected.
💻 Affected Systems
- Tenda AX1806
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise leading to persistent backdoor installation, network traffic interception, and lateral movement to other devices on the network.
Likely Case
Remote code execution allowing attackers to modify router settings, intercept traffic, or use the device as part of a botnet.
If Mitigated
Limited impact if the device is behind a firewall with strict inbound filtering and network segmentation.
🎯 Exploit Status
The detailed technical analysis includes proof-of-concept details, making exploitation straightforward for attackers with basic skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Check Tenda's official website for firmware updates. 2. If available, download the latest firmware. 3. Log into router admin interface. 4. Navigate to System Tools > Firmware Upgrade. 5. Upload and install the new firmware. 6. Reboot the router.
🔧 Temporary Workarounds
Disable remote management
allPrevent external access to the router's web interface
Log into router admin > System Tools > Remote Management > Disable
Restrict admin interface access
allLimit which IP addresses can access the router's management interface
Log into router admin > Security > Access Control > Set allowed IP ranges
🧯 If You Can't Patch
- Replace the vulnerable router with a different model from a vendor with better security practices
- Place the router behind a dedicated firewall with strict inbound filtering rules
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router admin interface: System Status > Firmware VersionCheck Version:
curl -s http://router-ip/goform/getStatus | grep versionVerify Fix Applied:
Verify firmware version is no longer v1.0.0.1 and test if the iptv configuration page accepts malformed input📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/setIptvInfo
- Multiple failed authentication attempts followed by iptv configuration changes
Network Indicators:
- Unusual outbound connections from router to unknown IPs
- Traffic patterns suggesting device compromise
