A vulnerability in the Layer 2 Tunneling Protocol (L2TP) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain L2TP packets. An attacker could exploit this vulnerability by sending crafted L2TP packets to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. Una vulnerabilidad en la función Layer 2 Tunneling Protocol (L2TP) del software Cisco IOS XE podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe al manejo inadecuado de ciertos paquetes L2TP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-l2tp-dos-eB5tuFmV • CWE-388: 7PK - Errors •

A vulnerability in Application Quality of Experience (AppQoE) and Unified Threat Defense (UTD) on Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to the mishandling of a crafted packet stream through the AppQoE or UTD application. An attacker could exploit this vulnerability by sending a crafted packet stream through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la Application Quality of Experience (AppQoE) y en el Unified Threat Defense (UTD) en el software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe al mal manejo de un flujo de paquetes manipulado a través de la aplicación AppQoE o UTD. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appqoe-utd-dos-p8O57p5y • CWE-456: Missing Initialization of a Variable •

A vulnerability in Cisco DNA Center could allow an unauthenticated, remote attacker to read and modify data in a repository that belongs to an internal service on an affected device. This vulnerability is due to insufficient access control enforcement on API requests. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to read and modify data that is handled by an internal service on the affected device. Una vulnerabilidad en Cisco DNA Center podría permitir que un atacante remoto no autenticado lea y modifique datos en un repositorio que pertenece a un servicio interno en un dispositivo afectado. Esta vulnerabilidad se debe a una aplicación insuficiente del control de acceso en las solicitudes de API. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-dnac-ins-acc-con-nHAVDRBZ • CWE-284: Improper Access Control •

A vulnerability in Cisco IOS XE Software for Cisco Catalyst 3650 and Catalyst 3850 Series Switches could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper resource management when processing traffic that is received on the management interface. An attacker could exploit this vulnerability by sending a high rate of traffic to the management interface. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el software Cisco IOS XE para los Switches Cisco Catalyst 3650 y Catalyst 3850 Series podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una gestión inadecuada de los recursos al procesar el tráfico que se recibe en la interfaz de gestión. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cat3k-dos-ZZA4Gb3r • CWE-770: Allocation of Resources Without Limits or Throttling •

A vulnerability in the Multicast Leaf Recycle Elimination (mLRE) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect handling of certain IPv6 multicast packets when they are fanned out more than seven times on an affected device. An attacker could exploit this vulnerability by sending a specific IPv6 multicast or IPv6 multicast VPN (MVPNv6) packet through the affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition. Una vulnerabilidad en la función Multicast Leaf Recycle Elimination (mLRE) del software Cisco IOS XE para los Routers de Servicios de Agregación Cisco ASR serie 1000 podría permitir que un atacante remoto no autenticado provoque que el dispositivo afectado se recargue, lo que resultaría en una condición de denegación de servicio (DoS). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-mlre-H93FswRz • CWE-823: Use of Out-of-range Pointer Offset •
