Detailsinfo

A vulnerability was found in Motorola C1 and M2 1.01/1.07. It has been declared as critical. This vulnerability affects an unknown part of the file /HNAP1. The manipulation of the argument tomography_ping_number 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. 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 SetNetworkTomographySettings API function, as demonstrated by shell metacharacters in the tomography_ping_number field.

The bug was discovered 02/19/2019. The weakness was published 03/07/2019. This vulnerability was named CVE-2019-9117 since 02/24/2019. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful 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.
