| Título | TOTOLINK A800R V4.1.2cu.5137_B20200730 Command Injection |
|---|
| Descrição | The TOTOLINK A800R router running firmware V4.1.2cu.5137_B20200730, a command injection flaw in the setDiagnosisCfg interface located within /lib/cste_modules/system.so. The vulnerability arises from insufficient sanitization of the ipDoamin parameter, which is concatenated into a shell command and executed via system(). The parameter passes through a Validity_check blocklist that fails to reject the newline character "\n", enabling remote attackers to inject and execute arbitrary operating-system commands. |
