Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
A vulnerability in the ipsecmgr process of Cisco ASR 5000 Series Software (StarOS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to insufficient validation of incoming Internet Key Exchange Version 2 (IKEv2) packets. An attacker could exploit this vulnerability by sending specifically malformed IKEv2 packets to an affected device. A successful exploit could allow the attacker to cause the ipsecmgr process to restart, which would disrupt ongoing IKE negotiations and result in a temporary DoS condition.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Esta vulnerabilidad se debe a una validaci\u00f3n insuficiente de los paquetes entrantes de Internet Key Exchange versi\u00f3n 2 (IKEv2). Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando paquetes IKEv2 espec\u00edficamente malformados a un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir que el atacante haga que el proceso ipsecmgr se reinicie, lo que interrumpir\u00eda las negociaciones IKE en curso y dar\u00eda como resultado una condici\u00f3n de DoS temporal. Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que solucionen esta vulnerabilidad."
