CVE-2018-4854
Estado: ModificadaAlta (8.8)—
A vulnerability has been identified in SICLOCK TC100 (All versions) and SICLOCK TC400 (All versions). An attacker with network access to port 69/udp could modify the administrative client stored on the device. If a legitimate user downloads and executes the modified client from the affected device, then he/she could obtain code execution on the client system.
