Attackers exploiting this vulnerability could leverage vulnerable instances to launch massive Denial-of-Service (DoS) amplification attacks with a factor as high as 2200 times, potentially making it one of the largest amplification attacks ever reported. This extremely high amplification factor allows for an under-resourced threat actor to have a significant impact on a targeted network and/or server via a reflective DoS amplification attack. During the first half of 2021, there have been a number of attacks using between 27 and 31 different vectors, plus an attacker can switch between them to make the attack harder to disrupt. 2021 A common example includes a Denial of Service (DoS) attack that repeatedly sends fake requests to clog (CVE-2021-36090) Impact There is no impact; F5 products are not affected by this vulnerability.
