CVE-2023-4410Public exploitNetwork attack vector

Root command execution via unvalidated ping address

Published Aug 18, 2023 · Updated Jul 3, 2025

OS command injection in TOTOLINK EX1200L EN_V9.3.5u.6146_B20201023 allows remote attackers to execute commands as root. setDiagnosisCfg inserts the unvalidated Ping Address value into a shell command used to run ping and stores output for getDiagnosisCfg. The public artifact does not establish whether authentication is required; successful exploitation exposes the command output.
