CWE-1334: Unauthorized Error Injection Can Degrade Hardware Redundancy

Unauthorized Error Injection Can Degrade Hardware Redundancy represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.

Executive Impact

Developer Pattern

CWE-1334 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

Developer And Remediation Guidance

How teams prevent and detect this weakness

Causes

  • Missing validation
  • Unsafe defaults
  • Insufficient authorization or memory-safety invariant

Remediation

  • Architecture and Design: Ensure the design does not allow error injection in modes intended for normal run-time operation. Provide access controls on interfaces for injecting errors.
  • Implementation: Disallow error injection in modes which are expected to be used for normal run-time operation. Provide access controls on interfaces for injecting errors.
  • Integration: Add an access control layer atop any unprotected interfaces for injecting errors.

Detection

  • Code review
  • SAST
  • DAST
  • Focused regression tests
