This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-F511 devices. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the diagapp component. 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 code in the context of root. Was ZDI-CAN-28750.","summary":"The diagapp component of Alpine iLX-F511 devices passes a user-supplied string into a system call without validating it.
