https://notcve.org/view.php?id=CVE-2021-1440
A vulnerability in the implementation of the Resource Public Key Infrastructure (RPKI) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the Border Gateway Protocol (BGP) process to crash, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of a specific RPKI to Router (RTR) Protocol packet header. ... A successful exploit could allow the attacker to cause a DoS condition because the BGP process could constantly restart and BGP routing could become unstable.Cisco has released software updates that address this vulnerability. ... Una vulnerabilidad en la implementación de la característica Resource Public Key Infrastructure (RPKI) del software Cisco IOS XR podría permitir que un atacante remoto no autenticado provoque el bloqueo del proceso del protocolo de puerta de enlace fronteriza (BGP), lo que daría lugar a una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe al manejo incorrecto de un encabezado de paquete específico del protocolo RPKI a enrutador (RTR). ... Una explotación exitosa podría permitir al atacante provocar una condición de DoS porque el proceso BGP podría reiniciarse constantemente y el enrutamiento BGP podría volverse inestable. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xrbgp-rpki-dos-gvmjqxbk https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-xss-webui-gQLSFyPM https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-sigverbypass-gPYXd6Mk https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-sma-info-disclo-VOu2GHbZ • CWE-617: Reachable Assertion •
