Glexia's Take · Automated analysis
CWE-1323: Improper Management of Sensitive Trace Data
Improper Management of Sensitive Trace Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Confidentiality: Read Memory: An adversary can read secret values if they are captured in debug traces and stored unsafely.
Developer Pattern
CWE-1323 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Automation confidence
high confidence from CWE-1323, 4.20.
Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.
Official CWE Definition
CWE-1323: Improper Management of Sensitive Trace Data
Trace data collected from several sources on the System-on-Chip (SoC) is stored in unprotected locations or transported to untrusted agents.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- 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.
Remediation
- Implementation: Tag traces to indicate owner and debugging privilege level (designer, OEM, or end user) needed to access that trace.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
