Device Unlock Credential Sharing

This vulnerability occurs when the secret keys or passwords required to unlock a device's hidden features are shared between multiple organizations, creating a chain of trust where sensitive access…

Definition

What is CWE-1273?

Device unlocking typically activates hidden debug or manufacturer modes, such as the ability to dump full system memory or bypass hardware protections. These powerful features are locked in production and require special credentials to access, often needed by different companies in the supply chain for testing and troubleshooting. The security risk escalates when these unlock credentials must be shared between separate entities like the chip designer, the manufacturer (foundry), and assembly testers. Each company may have vastly different security policies and levels of secrecy, turning a single secret into multiple points of potential exposure and significantly increasing the chance of a damaging credential leak.

Wie Angreifer es ausnutzen

Angreiferpfad Schritt für Schritt

1
Identifiziere einen Codepfad, der nicht vertrauenswürdige Eingaben ohne Validierung verarbeitet.
2
Erzeuge eine Payload, die das unsichere Verhalten auslöst — Injection, Traversal, Overflow oder Logik-Missbrauch.
3
Liefere die Payload über einen normalen Request aus und beobachte die Reaktion der Anwendung.
4
Iteriere, bis die Antwort Daten preisgibt, Angreifer-Code ausführt oder Berechtigungen eskaliert.

Verwundbares Codebeispiel

Vulnerable Other

This example shows how an attacker can take advantage of compromised credentials.

Verwundbar Other

Suppose a semiconductor chipmaker, "C", uses the foundry "F" for fabricating its chips. Now, F has many other customers in addition to C, and some of the other customers are much smaller companies. F has dedicated teams for each of its customers, but somehow it mixes up the unlock credentials and sends the unlock credentials of C to the wrong team. This other team does not take adequate precautions to protect the credentials that have nothing to do with them, and eventually the unlock credentials of C get leaked.

Sicheres Codebeispiel

Secure Other

When the credentials of multiple organizations are stored together, exposure to third parties occurs frequently.

Sicher Other

Vertical integration of a production company is one effective method of protecting sensitive credentials. Where vertical integration is not possible, strict access control and need-to-know are methods which can be implemented to reduce these risks.

What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.

Präventions-Checkliste

How to prevent CWE-1273

Integration Ensure the unlock credentials are shared with the minimum number of parties and with utmost secrecy. To limit the risk associated with compromised credentials, where possible, the credentials should be part-specific.
Manufacturing Ensure the unlock credentials are shared with the minimum number of parties and with utmost secrecy. To limit the risk associated with compromised credentials, where possible, the credentials should be part-specific.
