CVE-2020-14439

Unauthenticated command execution via undisclosed injection flaw

Published Jun 18, 2020 · Updated Aug 4, 2024

Command injection in NETGEAR Orbi WiFi 6 systems before 3.2.15.25 allows attackers to execute operating-system commands. NETGEAR has not disclosed the affected request handler or how it passes untrusted input to a command interpreter. Exploitation requires no credentials or user interaction but is limited to an adjacent network, where successful commands can read or alter device data and interrupt service.
