CWE-408: Incorrect Behavior Order: Early Amplification
Incorrect Behavior Order: Early Amplification represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Availability: DoS: Amplification DoS: Crash, Exit, or Restart DoS: Resource Consumption (CPU) DoS: Resource Consumption (Memory): System resources, CPU and memory, can be quickly consumed. This can lead to poor system performance or system crash.
Developer Pattern
CWE-408 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.

Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- This function prints the contents of a specified file requested by a user. This code first reads a specified file into memory, then prints the file if the user is authorized to see its contents. The read of the file into memory may be resource intensive and is unnecessary if the user is not allowed to see the file anyway.
Remediation
- Use safe APIs
- Centralize the control
- Add regression tests
- Review logs and telemetry for attempted abuse
Detection
- Code review
- SAST
- DAST
- Focused regression tests
