CVE-2024-52020

Authenticated command execution via wan_gateway injection

Published Nov 5, 2024 · Updated Nov 5, 2024

Command injection in NETGEAR R8500 Firmware 1.0.2.160 allows remote authenticated users to execute arbitrary OS commands. The wiz_fix2.cgi handler uses the untrusted wan_gateway value in an operating-system command without neutralizing command syntax. Reachability requires low-privilege access from an adjacent network, after which injected commands can read or alter data and interrupt service.
