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.
View on MITRESystems-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.
Security Identifier Decoders must be reviewed for design inconsistency and common weaknesses.
Access and programming flows must be tested in pre-silicon and post-silicon testing.

CWE-1294: Insecure Security Identifier Mechanism is a Common Weakness Enumeration (CWE) entry maintained by MITRE. 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.
If exploited, CWE-1294 (Insecure Security Identifier Mechanism) it can compromise Confidentiality, Integrity, Availability and Access Control, leading to outcomes such as Modify Memory, Read Memory, DoS: Resource Consumption (Other), Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity and Quality Degradation.
Recommended mitigations for CWE-1294 include: Security Identifier Decoders must be reviewed for design inconsistency and common weaknesses. Access and programming flows must be tested in pre-silicon and post-silicon testing.
CWE-1294 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.
A CWE (Common Weakness Enumeration) like CWE-1294 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
