CWE-405: Asymmetric Resource Consumption (Amplification)
What it is
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."
- Severity (our rating)

- Likelihood of exploit
- Not rated by MITRE
- Introduced during
- Architecture and Design, Implementation, Operation
- Exploited in the wild
- No CVE in CISA's catalog
In more detail
This can lead to poor performance due to "amplification" of resource consumption, typically in a non-linear fashion. This situation is worsened if the product allows malicious users or attackers to consume more resources than their access level permits.
What an attacker can do
- DoS: Amplification (Availability)
- DoS: Resource Consumption (CPU) (Availability)
- DoS: Resource Consumption (Memory) (Availability)
- DoS: Resource Consumption (Other) (Availability)
How to prevent it
Architecture and Design
- An application must make resources available to a client commensurate with the client's access level.
- 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.
