https://www.fragattacks.com/11 May 2021 — This website presents FragAttacks (fragmentation and aggregation attacks) which is a collection of new security vulnerabilities that affect Wi-Fi devices. An adversary that is within radio range of a victim can abuse these vulnerabilities to steal user information or attack devices. Three of the discovered vulnerabilities are design flaws in the Wi-Fi standard and therefore affect most devices. On top of this, several other vulnerabilities were discovered that are caused by widespread programming mistakes in Wi-Fi products. Experiments indicate that every Wi-Fi product is affected by at least one vulnerability and that most products are affected by several vulnerabilities.
The discovered vulnerabilities affect all modern security protocols of Wi-Fi, including the latest WPA3 specification. Even the original security protocol of Wi-Fi, called WEP, is affected. This means that several of the newly discovered design flaws have been part of Wi-Fi since its release in 1997! Fortunately, the design flaws are hard to abuse because doing so requires user interaction or is only possible when using uncommon network settings. As a result, in practice the biggest concern are the programming mistakes in Wi-Fi products since several of them are trivial to exploit.
Hopefully Mikrotik will release patched firmware and drivers soon.
