A vulnerability, which was classified as very critical, was found in NETGEAR MR60, MR70, MR90, MS60, MS70, MS90, RAX20, RAX200, RAX35, RAX35v2, RAX41, RAX41v2, RAX42, RAX42v2, RAX43, RAX43v2, RAX45, RAX49S, RAX50, RAX50v2, RAX54S, RAX54Sv2, RAX80, RAXE500, RS700, XR1000 and XR1000v2. This affects some unknown functionality. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A command injection vulnerability in certain affected NETGEAR Nighthawk devices allows a network-adjacent attacker with the ability to intercept and modify local network traffic (attacker in the middle) to compromise the confidentiality and integrity of the affected device.

The advisory is shared at netgear.com. This vulnerability is uniquely identified as CVE-2026-11739 since 06/09/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.
