Description
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.
