CVE-2024-2710
📋 TL;DR
This critical vulnerability in Tenda AC10U routers allows remote attackers to execute arbitrary code via a stack-based buffer overflow in the setSchedWifi function. Attackers can exploit this without authentication to potentially take full control of affected devices. All users of Tenda AC10U routers with firmware version 15.03.06.49 are affected.
💻 Affected Systems
- Tenda AC10U
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, creation of persistent backdoors, network pivoting, and data exfiltration.
Likely Case
Remote code execution allowing attackers to modify router settings, intercept network traffic, or join devices to botnets.
If Mitigated
Limited impact if devices are behind firewalls with strict inbound filtering and network segmentation.
🎯 Exploit Status
Public exploit details are available on GitHub, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch available. Contact Tenda support for firmware updates and monitor their website for security advisories.
🔧 Temporary Workarounds
Disable remote administration
allDisable remote management/administration features to prevent external exploitation.
Access router admin panel → Advanced Settings → System Tools → Remote Management → Disable
Network segmentation
allIsolate vulnerable routers in separate network segments with strict firewall rules.
🧯 If You Can't Patch
- Replace vulnerable devices with patched or different models
- Implement strict network access controls and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via admin panel: Login → Advanced Settings → System Status → Firmware VersionCheck Version:
Check via web interface or attempt to access /goform/openSchedWifi with monitoringVerify Fix Applied:
Verify firmware version is no longer 15.03.06.49 after any update📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/openSchedWifi
- Abnormal process execution on router
- Configuration changes without authorization
Network Indicators:
- Exploit traffic patterns to router management interface
- Unexpected outbound connections from router
