AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authenticated command injection vulnerability in multiple NETGEAR routers and WiFi systems allows attackers to execute arbitrary commands.
Vulnerability
This post-authentication command injection vulnerability affects multiple NETGEAR devices, including R7850, R7900P, R7960P, R8000, R8000P, RAX200, RAX75, RAX80, RBK752, RBK852, RBR750, RBR850, RBS750, and RBS850. The vulnerability exists in firmware versions prior to the fixed versions listed in the advisory [1]. An authenticated user can inject arbitrary commands through a vulnerable input field.
Exploitation
An attacker must have valid credentials to the device's web interface. The exact attack vector is not detailed in the advisory, but it involves sending crafted input that is not properly sanitized, leading to command injection. No user interaction beyond authentication is required.
Impact
Successful exploitation allows an authenticated attacker to execute arbitrary commands on the device with root privileges, potentially leading to full compromise of the device and network.
Mitigation
NETGEAR has released firmware updates for all affected models: R7850 to 1.0.5.74, R7900P/R7960P/R8000P to 1.4.2.84, R8000 to 1.0.4.74, RAX200/RAX75/RAX80 to 1.0.4.120, and Orbi systems (RBK752, RBK852, RBR750, RBR850, RBS750, RBS850) to 3.2.17.12 [1]. Users should update immediately. No workarounds are provided.
