Improper Restriction of Security Token Assignment

CWE-1259

The System-On-A-Chip (SoC) implements a Security Token mechanism to differentiate what actions are allowed or disallowed when a transaction originates from an entity. However, the Security Tokens are improperly protected, such as improperly restricting the assignment to trusted components.

We track 5 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.0.

How this weakness is prevented

  • Architecture and Design Implementation: Since the Security Tokens are integral for the maintenance of security in an SoC, they need to be protected properly. Security Token assignment review checks for design inconsistency and common weaknesses. Security-Token definition and programming flow is tested in both pre-silicon and post-silicon testing.
