Détail du CWE-1269

The product released to market is released in pre-production or manufacturing configuration.

Products in the pre-production or manufacturing stages are configured to have many debug hooks and debug capabilities, including but not limited to:

• Ability to override/bypass various cryptographic checks (including authentication, authorization, and integrity)
• Ability to read/write/modify/dump internal state (including registers and memory)
• Ability to change system configurations
• Ability to run hidden or private commands that are not allowed during production (as they expose IP).

The above is by no means an exhaustive list, but it alludes to the greater capability and the greater state of vulnerability of a product during it's preproduction or manufacturing state.

Complexity increases when multiple parties are involved in executing the tests before the final production version. For example, a chipmaker might fabricate a chip and run its own preproduction tests, following which the chip would be delivered to the Original Equipment Manufacturer (OEM), who would now run a second set of different preproduction tests on the same chip. Only after both of these sets of activities are complete, can the overall manufacturing phase be called "complete" and have the "Manufacturing Complete" fuse blown. However, if the OEM forgets to blow the Manufacturing Complete fuse, then the system remains in the manufacturing stage, rendering the system both exposed and vulnerable.

Mesures d’atténuation potentielles

Phases : Implementation
Ensure that there exists a marker for denoting the Manufacturing Complete stage and that the Manufacturing Complete marker gets updated at the Manufacturing Complete stage (i.e., the Manufacturing Complete fuse gets blown).
Phases : Integration
Ensure that there exists a marker for denoting the Manufacturing Complete stage and that the Manufacturing Complete marker gets updated at the Manufacturing Complete stage (i.e., the Manufacturing Complete fuse gets blown).

Notes de cartographie des vulnérabilités

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commentaire : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
