CVE-2023-4411Public exploitNetwork attack vector

Root command execution via unvalidated traceroute address

Published Aug 18, 2023 · Updated Aug 2, 2024

OS command injection in TOTOLINK EX1200L firmware EN_V9.3.5u.6146_B20201023 allows remote authenticated users to execute commands. The setTracerouteCfg handler inserts the unvalidated Trace Address value into a traceroute shell command before executing it. Access to the management CGI is required, and injected commands run as root with the ability to read or modify device data and interrupt service.
