CWE-410Insufficient Resource Pool

Description

The product's resource pool is not large enough to handle peak demand, which allows an attacker to prevent others from accessing the resource by using a (relatively) large number of requests for resources.

Frequently the consequence is a "flood" of connection or sessions.

Common consequences

• Availability,Integrity,Other→DoS: Crash, Exit, or Restart,Other
  Floods often cause a crash or other problem besides denial of the resource itself; these are likely examples of *other* vulnerabilities, not an insufficient resource pool.

Potential mitigations

• Architecture and Design
  Do not perform resource-intensive transactions for unauthenticated users and/or invalid requests.
• Architecture and Design
  Consider implementing a velocity check mechanism which would detect abusive behavior.
• Operation
  Consider load balancing as an option to handle heavy loads.
• Implementation
  Make sure that resource handles are properly closed when no longer needed.
• Architecture and Design
  Identify the system's resource intensive operations and consider protecting them from abuse (e.g. malicious automated script which runs the resources out).
