Tên: 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."

Hậu quả phổ biến

Phạm vi	Tác động	Khả năng xảy ra
Availability	DoS: Amplification, DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Resource Consumption (Other) Ghi chú: 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

CVE-1999-0513	Classic "Smurf" attack, using spoofed ICMP packets to broadcast addresses.
CVE-2003-1564	Parsing library allows XML bomb
CVE-2004-2458	Tool creates directories before authenticating user.
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.

Các biện pháp giảm thiểu tiềm năng

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.
