CWE-1429: Missing Security-Relevant Feedback for Unexecuted Operations in Hardware Interface
Description
The product has a hardware interface that silently discards operations in situations for which feedback would be security-relevant, such as the timely detection of failures or attacks.
- Abstraction
- BaseA weakness specific enough to point to detection and prevention methods.
- Likelihood of exploit
- Not rated by MITRE
- Status
- Incomplete
Common consequences
- Confidentiality
Read Memory; Read Files or Directories
Critical data may be exposed if operations are unexecuted or discarded silently, allowing attackers to exploit the lack of feedback.
- Integrity
Modify Memory; Modify Files or Directories
Operations may proceed based on incorrect assumptions, potentially causing data corruption or incorrect system behavior. In integrity-sensitive contexts, failing to signal that an operation did not occur as expected can mask errors that disrupt data consistency. Without feedback, the mitigation measures that should...
- Availability
DoS: Resource Consumption (Memory); DoS: Crash, Exit, or Restart
Unhandled discarded operations can lead to resource exhaustion, triggering system crashes or denial of service. For availability, consistent feedback is crucial. Without proper notification of discarded operations, administrators or other authorized entities might miss early warning signs of resource imbalances. This...
Potential mitigations
- Architecture and DesignEffectiveness: High
Incorporate logging and feedback mechanisms during the design phase to ensure proper handling of discarded operations.
- ImplementationEffectiveness: Moderate
Developers should ensure that every critical operation includes proper logging or error feedback mechanisms.
