| Title | TOTOLINK X18 (AX1800 Dual Band WiFi6 Gigabit Router, model C834JR) V9.1.0cu.2024_B20220329 Command Injection |
|---|
| Description | The TOTOLINK X18 router running firmware V9.1.0cu.2024_B20220329 is susceptible to a command injection flaw in the setSyslogCfg interface located within /web/cgi-bin/cstecgi.cgi. The vulnerability arises from a complete absence of sanitization of the rtLogServer parameter, which is concatenated into a shell command and executed via CsteSystem() (a wrapper around system()). The value is neither escaped nor screened, so ordinary shell metacharacters such as ; are sufficient. |
