The System-on-Chip (SoC) does not have unique, immutable identifiers for each of its components.
View on MITREA System-on-Chip (SoC) comprises several components (IP) with varied trust requirements. It is required that each IP is identified uniquely and should distinguish itself from other entities in the SoC without any ambiguity. The unique secured identity is required for various purposes. Most of the time the identity is used to route a transaction or perform certain actions, including resetting, retrieving a sensitive information, and acting upon or on behalf of something else. There are several variants of this weakness: A "missing" identifier is when the SoC does not define any mechanism to uniquely identify the IP. An "insufficient" identifier might provide some defenses - for example, against the most common attacks - but it does not protect against everything that is intended. A "misconfigured" mechanism occurs when a mechanism is available but not implemented correctly. An "ignored" identifier occurs when the SoC/IP has not applied any policies or does not act upon the identifier securely.
Every identity generated in the SoC should be unique and immutable in hardware. The actions that an IP is trusted or not trusted should be clearly defined, implemented, configured, and tested. If the definition is implemented via a policy, then the policy should be immutable or protected with clear authentication and authorization.

CWE-1192: Improper Identifier for IP Block used in System-On-Chip (SOC) is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The System-on-Chip (SoC) does not have unique, immutable identifiers for each of its components. A System-on-Chip (SoC) comprises several components (IP) with varied trust requirements. It is required that each IP is identified uniquely and should distinguish itself from other entities in the SoC without any ambiguity. The unique secured identity is required for various purposes.

An "ignored" identifier occurs when the SoC/IP has not applied any policies or does not act upon the identifier securely.
If exploited, CWE-1192 (Improper Identifier for IP Block used in System-On-Chip (SOC)) it can compromise Access Control, leading to outcomes such as Bypass Protection Mechanism.
Recommended mitigations for CWE-1192 include: Every identity generated in the SoC should be unique and immutable in hardware. The actions that an IP is trusted or not trusted should be clearly defined, implemented, configured, and tested. If the definition is implemented via a policy, then the policy should be immutable or protected with clear authentication and authorization.
CWE-1192 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-1192 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.
