CVSS: 8.6EPSS: 0%CPEs: 72EXPL: 0CVE-2021-34720 – Cisco IOS XR Software IP Service Level Agreements and Two-Way Active Measurement Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34720
A vulnerability in the IP Service Level Agreements (IP SLA) responder and Two-Way Active Measurement Protocol (TWAMP) features of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause device packet memory to become exhausted or cause the IP SLA process to crash, resulting in a denial of service (DoS) condition. This vulnerability exists because socket creation failures are mishandled during the IP SLA and TWAMP processes. An attacker could exploit this vulnerability by sending specific IP SLA or TWAMP packets to an affected device. A successful exploit could allow the attacker to exhaust the packet memory, which will impact other processes, such as routing protocols, or crash the IP SLA process. Una vulnerabilidad en las funciones de respuesta de los Acuerdos de Nivel de Servicio IP (IP SLA) y del Protocolo de Medición Activa de Dos Vías (TWAMP) de Cisco IOS XR Software podría permitir a un atacante remoto no autenticado causar el agotamiento de la memoria de paquetes del dispositivo o causar el bloqueo del proceso IP SLA, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipsla-ZA3SRrpP • CWE-771: Missing Reference to Active Allocated Resource •
