CVE-2023-39618Network attack vector

Unauthenticated command execution via setTracerouteCfg

Published Aug 21, 2023 · Updated Oct 7, 2024

OS command injection in TOTOLINK X5000R B20210419 allows remote attackers to execute arbitrary commands through setTracerouteCfg. The public report identifies the interface, but the accessible record does not disclose which request parameter reaches the operating-system command or how input is assembled. Network access to the router's management service is sufficient; successful exploitation can read or alter router data and interrupt service.
