CVE-2024-57231
📋 TL;DR
This CVE describes a command injection vulnerability in NETGEAR RAX5 routers that allows attackers to execute arbitrary commands on the device. Attackers can exploit this by sending specially crafted requests to the vulnerable function, potentially gaining full control of the router. All users of affected NETGEAR RAX5 routers with vulnerable firmware are at risk.
💻 Affected Systems
- NETGEAR RAX5 (AX1600 WiFi Router)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the router allowing attackers to intercept all network traffic, install persistent malware, pivot to internal network devices, and use the router as part of a botnet.
Likely Case
Attackers gain remote code execution on the router, enabling them to modify DNS settings, intercept credentials, and potentially access connected devices on the local network.
If Mitigated
With proper network segmentation and firewall rules, the impact is limited to the router itself, though attackers could still disrupt internet connectivity and potentially access other devices on the same network segment.
🎯 Exploit Status
The GitHub reference contains technical details about the vulnerability, making exploitation straightforward for attackers with basic skills.
