What is CWE-1323?

This vulnerability occurs when sensitive trace data from a System-on-Chip (SoC), such as information from CPUs or cryptographic modules, is stored in unsecured memory or transmitted to unauthorized debuggers, potentially exposing confidential information.
Modern System-on-Chip (SoC) designs incorporate specialized tracing hardware to monitor internal signals in real-time. This capability is essential for debugging and validating complex hardware and software interactions. However, these traces often capture highly sensitive data from security-critical components like cryptographic engines and processor cores. If this collected trace data isn't properly secured—either by storing it in unprotected memory or failing to tag it with security metadata—it becomes accessible to unauthorized agents. An untrusted software debugger could read unprotected memory to extract secrets, while a hardware debugger might access improperly tagged traces, leading to the exposure of confidential information and system compromise.

Cómo lo explotan los atacantes

Ruta del atacante paso a paso

  1. 1

    Identifica una ruta de código que maneje entrada no confiable sin validación.

  2. 2

    Crea un payload que ejercite el comportamiento inseguro — inyección, traversal, overflow o abuso de lógica.

  3. 3

    Envía el payload a través de una solicitud normal y observa la reacción de la aplicación.

  4. 4

    Itera hasta que la respuesta filtre datos, ejecute código del atacante o escale privilegios.

Ejemplo de código vulnerable

Vulnerable Other

In a SoC, traces generated from sources include security-sensitive IP blocks such as CPU (with tracing information such as instructions executed and memory operands), on-chip fabric (e.g., memory-transfer signals, transaction type and destination, and on-chip-firewall-error signals), power-management IP blocks (e.g., clock- and power-gating signals), and cryptographic coprocessors (e.g., cryptographic keys and intermediate values of crypto operations), among other non-security-sensitive IP blocks including timers and other functional blocks. The collected traces are then forwarded to the debug and trace interface used by the external hardware debugger.

Vulnerable Other
The traces do not have any privilege level attached to them. All collected traces can be viewed by any debugger (i.e., SoC designer, OEM debugger, or end user).
Ejemplo de código seguro

Secure Other

Seguro Other
Some of the traces are SoC-design-house secrets, while some are OEM secrets. Few are end-user secrets and the rest are not security-sensitive. Tag all traces with the appropriate, privilege level at the source. The bits indicating the privilege level must be immutable in their transit from trace source to the final, trace sink. Debugger privilege level must be checked before providing access to traces.
What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
