提出 #813910: Totolink A8000RU 7.1cu.643_b20200521 Command Injection情報

タイトルTotolink A8000RU 7.1cu.643_b20200521 Command Injection
説明A pre‑authentication OS command injection vulnerability exists in the `setL2tpServerCfg` functionality exposed via the web management interface (`/cgi-bin/cstecgi.cgi`) of the TOTOLINK A8000RU 7.1cu.643_b20200521 router. The CGI handler retrieves user‑controlled input from the HTTP parameter `lanIp`, embeds it directly into a shell command string using `sprintf`, and executes it via `CsteSystem()` without any sanitization or escaping. As a result, a remote attacker with network access to the web interface can inject arbitrary shell commands and execute them with root privileges on the device, without authentication.
