Insecure Security Identifier Mechanism

Description

The System-on-Chip (SoC) implements a Security Identifier mechanism to differentiate what actions are allowed or disallowed when a transaction originates from an entity. However, the Security Identifiers are not correctly implemented.

Systems-On-Chip (Integrated circuits and hardware engines) implement Security Identifiers to differentiate/identify actions originated from various agents. These actions could be 'read', 'write', 'program', 'reset', 'fetch', 'compute', etc. Security identifiers are generated and assigned to every agent in the System (SoC) that is either capable of generating an action or receiving an action from another agent. Every agent could be assigned a unique, Security Identifier based on its trust level or privileges. A broad class of flaws can exist in the Security Identifier process, including but not limited to missing security identifiers, improper conversion of security identifiers, incorrect generation of security identifiers, etc.

Common Consequences

Scope: Confidentiality, Integrity, Availability, Access Control

Impact: Modify Memory, Read Memory, DoS: Resource Consumption (Other), Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity, Quality Degradation
