FunJSQ, a third-party module integrated on some NETGEAR routers and Orbi WiFi Systems, exposes an HTTP server over the LAN interface of affected devices. This interface is vulnerable to unauthenticated arbitrary command injection through the funjsq_access_token parameter. This affects R6230 before 1.1.0.112, R6260 before 1.1.0.88, R7000 before 1.0.11.134, R8900 before 1.0.5.42, R9000 before 1.0.5.42, and XR300 before 1.0.3.72 and Orbi RBR20 before 2.7.2.26, RBR50 before 2.7.4.26, RBS20 before 2.7.2.26, and RBS50 before 2.7.4.26.
Executive ViewAI
NETGEAR routers and Orbi WiFi Systems containing the FunJSQ module are vulnerable to unauthenticated remote code execution via LAN access, allowing attackers to fully compromise affected devices without authentication. Organizations using these devices face immediate risk of network infiltration, data theft, and lateral movement into corporate systems, with no vendor patch currently available.
Segment affected devices on isolated VLANs with restricted access; implement firewall rules to block inbound connections to the FunJSQ HTTP service; disable or uninstall the FunJSQ module if the router firmware allows it; monitor network traffic for suspicious command injection patterns; consider disabling remote management features on affected devices; establish continuous device monitoring for unauthorized access attempts.
