Weakness (CWE)
CWE-405: Amplification
The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is "asymmetric."
How to prevent it (3 mitigations)
-
Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
-
Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
-
System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
