Summary
The vulnerability in Kenwood DNR1007XR in the startUpdateProcess method allows command injection. An attacker with physical access, without authentication, can exploit the lack of input validation to execute arbitrary code as root.
Risk Assessment
The risk is the potential for an attacker with physical access to gain control of the device and execute arbitrary system commands, potentially disrupting operations or compromising data.
Recommendation
It is recommended to restrict physical access to the device and apply vendor patches if available to mitigate the vulnerability.

Original NVD description (English source)
Kenwood DNR1007XR startUpdateProcess Command Injection Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Kenwood DNR1007XR devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the startUpdateProcess method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. Was ZDI-CAN-28981.
