CVE-2019-9121

Estado: ModificadaCrítica (9.8)—

An issue was discovered on Motorola C1 and M2 devices with firmware 1.01 and 1.07 respectively. This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 POST request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body for the SetSmartQoSSettings API function, as demonstrated by shell metacharacters in the smartqos_priority_devices field.
