Technical details
This is a symlink-following vulnerability in the firmware update process of the Kenwood DNR1007XR receiver. The flaw allows an unauthenticated, physically present attacker to abuse the update service by creating a symbolic link, enabling arbitrary file movement to locations of attacker control. By leveraging this primitive, an attacker can execute arbitrary code in the root security context. Physical access to the device is required; no authentication is needed. Kenwood released a firmware update addressing this issue, as documented on their firmware update page.
