CVE-2019-20706Network attack vector

Authenticated command execution

Published Apr 16, 2020 · Updated Aug 5, 2024

Command injection in NETGEAR R7800 before 1.0.2.60 and XR500 before 2.3.2.32 allows remote authenticated users to execute commands. NETGEAR has not published the affected endpoint, parameter, or command-construction operation that mishandles untrusted input. An authenticated session on an adjacent network is required; successful exploitation executes unspecified commands in the router firmware context.
