A command injection vulnerability exists in certain NETGEAR Nighthawk devices that allows a network-adjacent attacker capable of intercepting and modifying local network traffic to compromise the device's confidentiality and integrity. The vulnerability requires the attacker to be in a man-in-the-middle position on the local network. No specific affected versions or patches are currently identified. The severity is assessed as medium based on the available information.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-11739) is a command injection flaw in some NETGEAR Nighthawk devices. An attacker positioned on the local network who can intercept and modify traffic may exploit this vulnerability to execute arbitrary commands on the device, impacting its confidentiality and integrity. The CVSS 4.0 vector indicates the attack vector is adjacent network with high attack complexity and privileges not required. There is no indication of known exploits in the wild or available patches at this time.
Potential Impact
Successful exploitation allows an attacker with network-adjacent access and the ability to intercept and modify local traffic to compromise the confidentiality and integrity of the affected device. This could lead to unauthorized command execution on the device. No information about availability impact or further consequences is provided.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fixes or workarounds are currently documented. Until a patch is available, minimizing exposure to man-in-the-middle attacks on the local network is advisable.
