AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authenticated command injection in multiple NETGEAR WiFi systems allows arbitrary command execution.
Vulnerability
A post-authentication command injection vulnerability exists in multiple NETGEAR Orbi WiFi system models, including RBK752, RBR750, RBS750, RBK852, RBR850, and RBS850, running firmware versions prior to 3.2.16.6 [1]. An authenticated user can inject arbitrary commands through a vulnerable input field.
Exploitation
An attacker must have valid authentication credentials to the affected device. The vulnerability can be exploited by sending specially crafted input to a vulnerable endpoint, leading to command injection [1]. No user interaction beyond authentication is required.
Impact
Successful exploitation allows an authenticated attacker to execute arbitrary commands on the underlying operating system with elevated privileges, potentially leading to full compromise of the device [1].
Mitigation
NETGEAR has released firmware version 3.2.16.6 to fix this vulnerability. Users are strongly advised to upgrade to the latest firmware as soon as possible [1]. No workarounds are available.
