CVE-2022-33203 – BIG-IP APM and F5 SSL Orchestrator vulnerability CVE-2022-33203
https://notcve.org/view.php?id=CVE-2022-33203
In BIG-IP Versions 16.1.x before 16.1.3, 15.1.x before 15.1.6.1, and 14.1.x before 14.1.5, when a BIG-IP APM access policy with Service Connect agent is configured on 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. En BIG-IP versiones 16.1.x anteriores a 16.1.3, 15.1.x anteriores a 15.1.6.1 y 14.1.x anteriores a 14.1.5, cuando es configurado una política de acceso de BIG-IP APM con el agente Service Connect en un servidor virtual, las peticiones no reveladas pueden causar un aumento en el uso de los recursos de memoria. Nota: Las versiones de software que han alcanzado el fin del soporte técnico (EoTS) no son evaluadas • https://support.f5.com/csp/article/K52534925 • CWE-400: Uncontrolled Resource Consumption •
CVE-2002-20001
https://notcve.org/view.php?id=CVE-2002-20001
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 •
