Detailsinfo

A vulnerability was found in Motorola C1 and M2 1.01/1.07. It has been rated as critical. This issue affects an unknown code of the file /HNAP1. The manipulation of the argument system_time_timezone as part of a Shell Metacharacter leads to a os command injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is 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 SetNTPServerSettings API function, as demonstrated by shell metacharacters in the system_time_timezone field.
