Nama: Asymmetric Resource Consumption (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."

AvailabilityDoS: Amplification, DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Resource Consumption (Other)

Catatan: 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. Sometimes this is a factor in "flood" attacks, but other types of amplification exist.		High

Classic "Smurf" attack, using spoofed ICMP packets to broadcast addresses.

CVE-2003-1564

Parsing library allows XML bomb

CVE-2004-2458

CVE-2020-10735

Python has "quadratic complexity" issue when converting string to int with many digits in unexpected bases

CVE-2020-5243

server allows ReDOS with crafted User-Agent strings, due to overlapping capture groups that cause excessive backtracking.

CVE-2013-5211

composite: NTP feature generates large responses (high amplification factor) with spoofed UDP source addresses.

CVE-2002-20001

Diffie-Hellman (DHE) Key Agreement Protocol allows attackers to send arbitrary numbers that are not public keys, which causes the server to perform expensive, unnecessary computation of modular exponentiation.

CVE-2022-40735

The Diffie-Hellman Key Agreement Protocol allows use of long exponents, which are more computationally expensive than using certain "short exponents" with particular properties.

Mitigasi yang Memungkinkan

Phases : Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Phases : Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
Phases : System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
