CVE-2025-12945
📋 TL;DR
This vulnerability allows authenticated administrators on NETGEAR Nighthawk R7000P routers to execute arbitrary operating system commands through command injection. Attackers with admin credentials can gain full system control. All R7000P routers running firmware versions up to 1.3.3.154 are affected.

📦 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 networks, and use the router for further attacks.
Likely Case
Attackers with stolen or default admin credentials gain full router control to monitor traffic, change DNS settings, or disable security features.
If Mitigated
Limited impact if strong unique admin passwords are used and network segmentation isolates the router management interface.
🎯 Exploit Status
Requires admin credentials but command injection is straightforward once authenticated.
