Classified as CWE-295 (Improper Certificate Validation). Affects Rbr20 Firmware. FunJSQ, a third-party module integrated on some NETGEAR routers and Orbi WiFi Systems, does not properly validate TLS certificates when downloading update packages through its auto-update mechanism. An attacker (suitably positioned on the network) could intercept the update request and deliver a malicious update package in order to gain arbitrary code execution on affected devices. 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 b

Executive ViewAI
NETGEAR routers and Orbi WiFi systems are vulnerable to man-in-the-middle attacks during firmware updates due to improper TLS certificate validation in the FunJSQ module. An attacker can intercept and inject malicious firmware, potentially compromising network security and customer data across affected deployments. No patch is currently available from the vendor.
Disable auto-update feature on affected devices and manually control update timing; implement network segmentation to restrict firmware update traffic to trusted internal repositories only; deploy SSL/TLS inspection and certificate pinning at network egress points; monitor outbound connections from affected devices to update servers; disable FunJSQ module if functionally optional; require VPN for remote device management; implement endpoint detection and response (EDR) on connected systems to detect post-compromise indicators.
