CVE-2023-51098Public exploitNetwork attack vector

Authenticated command execution via diagnostic parameter

Published Dec 26, 2023 · Updated Aug 2, 2024

Command injection in Tenda W9 1.0.0.7(4456)_CN allows remote authenticated users to execute shell commands through its web interface. The formSetDiagnoseInfo handler inserts the cmd HTTP parameter into a command string without neutralizing shell metacharacters. Access to the administrative web session is required; successful exploitation runs arbitrary commands on the access point, including starting a remote shell service.
