CVE-2024-10281
📋 TL;DR
A critical stack-based buffer overflow vulnerability in Tenda RX9 and RX9 Pro routers allows remote attackers to execute arbitrary code by manipulating the SetStaticRouteCfg function. This affects users running vulnerable firmware versions on these specific router models. Successful exploitation could lead to complete device compromise.
💻 Affected Systems
- Tenda RX9
- Tenda RX9 Pro
📦 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 to internal devices.
Likely Case
Router takeover enabling man-in-the-middle attacks, DNS hijacking, and creation of persistent backdoor access.
If Mitigated
Limited impact if routers are behind firewalls with strict inbound filtering and not internet-facing.
🎯 Exploit Status
Public exploit details available on Gitee. Remote exploitation without authentication makes this highly attractive to attackers.

🧯 If You Can't Patch
- Replace vulnerable routers with patched or different models
- Implement strict network monitoring for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin interface under System Status or Firmware Upgrade sectionCheck Version:
curl -s http://router-ip/goform/getStatus | grep versionVerify Fix Applied:
Verify firmware version is newer than 22.03.02.20 and test if SetStaticRouteCfg endpoint still exists📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/SetStaticRouteCfg
- Router reboot events
- Failed authentication attempts to admin interface
Network Indicators:
- Unusual outbound connections from router
- DNS configuration changes
- New static route entries
SIEM Query:
