CWE-1297

Unprotected Confidential Information on Device is Accessible by OSAT Vendors

High

Description

The product does not adequately protect confidential information on the device from being accessed by Outsourced Semiconductor Assembly and Test (OSAT) vendors.

Potential Impact

How to Fix

Architecture and Design

Ensure that when an OSAT vendor is allowed to access test interfaces necessary for preproduction and returned parts, the vendor only pulls the minimal information necessary. Also, architect the product in such a way that, when an "unlock device" request comes, it only unlocks that specific part and not all the parts for that product line. Ensure that the product's non-volatile memory (NVM) is scrubbed of all confidential information and secrets before handing it over to an OSAT. Arrange to secure all communication between an OSAT facility and the chipmaker.
