CVE-2023-38563

Unauthenticated OS command execution via undisclosed input

Published Sep 6, 2023 · Updated Sep 26, 2024

OS command injection in TP-Link Archer C1200, C9, and C90 firmware allows unauthenticated remote attackers on adjacent networks to run OS commands. Public advisories do not identify the request parameter, handler, or command-building operation that accepts untrusted input. The access gate is proximity to the router's network, with neither authentication nor user interaction required.
