CVE-2024-57235
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on NETGEAR RAX5 routers by injecting malicious commands through the iface parameter. Attackers can gain full control of affected routers, potentially compromising all connected devices. Only NETGEAR RAX5 (AX1600) routers running vulnerable firmware are affected.
💻 Affected Systems
- NETGEAR RAX5 (AX1600 WiFi Router)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete router compromise leading to full network takeover, credential theft, malware deployment to all connected devices, and persistent backdoor installation.
Likely Case
Router compromise allowing traffic interception, DNS hijacking, credential harvesting, and lateral movement to connected devices.
If Mitigated
Limited impact if router is behind firewall with restricted WAN access, though internal network devices remain at risk.
🎯 Exploit Status
Public GitHub repository contains proof-of-concept exploit code. Command injection vulnerabilities are typically easy to weaponize.

Network segmentation
allIsolate router management interface from untrusted networks
🧯 If You Can't Patch
- Replace router with different model or vendor
- Place router behind dedicated firewall with strict inbound rules
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router admin interface under Advanced > Administration > Firmware UpdateCheck Version:
curl -s http://router-ip/currentsetting.htm | grep FirmwareVerify Fix Applied:
Verify firmware version is no longer V1.0.2.26 and test if command injection is possible📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in router logs
- Multiple failed login attempts followed by successful access
- Suspicious iface parameter values in HTTP requests
Network Indicators:
- Unusual outbound connections from router
- DNS queries to malicious domains
- Unexpected SSH/Telnet traffic from router
SIEM Query:
source="router_logs" AND ("iface=" OR "vif_enable") AND (cmd.exe OR /bin/sh OR wget OR curl)
