A vulnerability, which was classified as critical, has been found in Motorola C1 and M2 1.01/1.07. Affected by this issue is an unknown function of the file /HNAP1. The manipulation of the argument smartqos_priority_devices as part of a Shell Metacharacter leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 02/19/2019. The weakness was shared 03/07/2019. This vulnerability is handled as CVE-2019-9121 since 02/24/2019. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

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.
