CVE-2024-57229
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on NETGEAR RAX5 routers by injecting malicious input into the devname parameter of the reset_wifi function. Attackers can gain full control of affected routers, potentially compromising all network traffic. All users of NETGEAR RAX5 routers with vulnerable firmware are affected.
💻 Affected Systems
- NETGEAR RAX5 (AX1600 WiFi Router)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete router compromise allowing attackers to intercept all network traffic, install persistent malware, pivot to internal network devices, and use the router as a botnet node.
Likely Case
Router takeover enabling traffic interception, DNS hijacking, credential theft from unencrypted traffic, and installation of cryptocurrency miners or other malware.
If Mitigated
Limited impact if router is behind firewall with restricted WAN access, though internal attackers could still exploit if they gain network access.
🎯 Exploit Status
Public proof-of-concept available on GitHub. Exploitation requires network access to router management interface but no authentication.
