CVE-2019-20718

Authenticated command execution

Published Apr 16, 2020 · Updated Aug 5, 2024

Command injection in NETGEAR router firmware allows remote authenticated users on an adjacent network to execute arbitrary commands. NETGEAR has not published the affected interface, parameter, or input-handling operation that passes untrusted data to a command interpreter. Access requires authentication with high privileges and network proximity to the device; successful exploitation grants command execution with confidentiality, integrity, and availability impact.
