CVE-2023-29562
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on TP-Link TL-WPA7510 devices via a stack overflow in the operation parameter at /admin/locale. Attackers can gain full control of affected devices without authentication. All users of TP-Link TL-WPA7510 (EU)_V2_190125 firmware are affected.
💻 Affected Systems
- TP-Link TL-WPA7510
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise leading to persistent backdoor installation, network pivoting, and data exfiltration.
Likely Case
Remote code execution allowing attackers to modify device settings, intercept traffic, or join botnets.
If Mitigated
Limited impact if devices are behind firewalls with strict inbound filtering and network segmentation.
🎯 Exploit Status
Public GitHub repository contains proof-of-concept code. Exploitation requires sending a crafted HTTP request to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Check TP-Link website for firmware updates. 2. Download latest firmware for TL-WPA7510. 3. Log into device web interface. 4. Navigate to System Tools > Firmware Upgrade. 5. Upload and install new firmware. 6. Reboot device.
🔧 Temporary Workarounds
Network Isolation
allPlace devices on isolated VLAN with no internet access and strict firewall rules.
Access Control
linuxBlock external access to device web interface (port 80/443) using firewall rules.
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Replace vulnerable devices with updated models or different vendors
- Implement strict network segmentation and monitor for exploit attempts
🔍 How to Verify
Check if Vulnerable:
Check firmware version in device web interface under System Tools > Firmware Upgrade. If version is EU_V2_190125, device is vulnerable.Check Version:
curl -s http://device-ip/ | grep -i firmwareVerify Fix Applied:
Verify firmware version has been updated to a version later than EU_V2_190125.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /admin/locale with long operation parameters
- Unusual process execution or network connections from device
Network Indicators:
- HTTP POST requests to /admin/locale with oversized payloads
- Unexpected outbound connections from device
