A vulnerability classified as critical was found in Motorola C1 and M2 1.01/1.07. Affected by this vulnerability is some unknown processing of the file /HNAP1. The manipulation of the argument wl00_maclist as part of a Shell Metacharacter leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 SetWLanACLSettings API function, as demonstrated by shell metacharacters in the wl(0).(0)_maclist field.

The bug was discovered 02/19/2019. The weakness was presented 03/07/2019. This vulnerability is known as CVE-2019-9120 since 02/24/2019. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 16 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
