CVSS: 7.5EPSS: 0%CPEs: 25EXPL: 0CVE-2023-22664 – BIG-IP HTTP/2 profile vulnerability
https://notcve.org/view.php?id=CVE-2023-22664
On BIG-IP versions 17.0.x before 17.0.0.2 and 16.1.x before 16.1.3.3, and BIG-IP SPK starting in version 1.6.0, when a client-side HTTP/2 profile and the HTTP MRF Router option are enabled for a virtual server, undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. • https://my.f5.com/manage/s/article/K56676554 • CWE-400: Uncontrolled Resource Consumption •

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE. El Protocolo de Acuerdo de Claves Diffie-Hellman permite a atacantes remotos (del lado del cliente) enviar números arbitrarios que en realidad no son claves públicas, y desencadenar costosos cálculos de exponenciación modular DHE del lado del servidor, también se conoce como un ataque D(HE)ater. • https://cert-portal.siemens.com/productcert/pdf/ssa-506569.pdf https://dheatattack.com https://dheatattack.gitlab.io https://github.com/Balasys/dheater https://github.com/mozilla/ssl-config-generator/issues/162 https://gitlab.com/dheatattack/dheater https://ieeexplore.ieee.org/document/10374117 https://support.f5.com/csp/article/K83120834 https://www.arubanetworks.com/assets/alert/ARUBA-PSA-2022-004.txt https://www.openssl.org/blog/blog/2022/10/21/tls-groups-configuration https: • CWE-400: Uncontrolled Resource Consumption •
