Uncontrolled Resource Consumption
CWE-400
The product does not properly control the allocation and maintenance of a limited resource.
We track 1,380 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 7.6. 8 have been exploited in real attacks.
How this weakness is prevented
- Architecture and Design: Ensure that protocols have specific limits of scale placed on them.
- Implementation: Ensure that all failures in resource allocation place the system into a safe posture.
