A vulnerability in the SSH client feature of Cisco IOS XR Software for Cisco 8000 Series Routers and Cisco Network Convergence System (NCS) 540 Series and 5700 Series Routers could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient validation of arguments that are included with the SSH client CLI command. An attacker with low-privileged access to an affected device could exploit this vulnerability by issuing a crafted SSH client command to the CLI. A successful exploit could allow the attacker to elevate privileges to root on the affected device. Una vulnerabilidad en la función de cliente SSH del software Cisco IOS XR para los enrutadores Cisco de la serie 8000 y los enrutadores Cisco Network Convergence System (NCS) de las series 540 y 5700 podría permitir que un atacante local autenticado eleve los privilegios en un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-ssh-privesc-eWDMKew3 • CWE-266: Incorrect Privilege Assignment •

A vulnerability in the PPP over Ethernet (PPPoE) termination feature of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, adjacent attacker to crash the ppp_ma process, resulting in a denial of service (DoS) condition. This vulnerability is due to the improper handling of malformed PPPoE packets that are received on a router that is running Broadband Network Gateway (BNG) functionality with PPPoE termination on a Lightspeed-based or Lightspeed-Plus-based line card. An attacker could exploit this vulnerability by sending a crafted PPPoE packet to an affected line card interface that does not terminate PPPoE. A successful exploit could allow the attacker to crash the ppp_ma process, resulting in a DoS condition for PPPoE traffic across the router. Una vulnerabilidad en la función de terminación de PPP sobre Ethernet (PPPoE) del software Cisco IOS XR para los enrutadores de servicios de agregación Cisco ASR serie 9000 podría permitir que un atacante adyacente no autenticado bloquee el proceso ppp_ma, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe al manejo inadecuado de paquetes PPPoE con formato incorrecto que se reciben en un enrutador que ejecuta la funcionalidad Broadband Network Gateway (BNG) con terminación PPPoE en una tarjeta de línea basada en Lightspeed o Lightspeed-Plus. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-pppma-JKWFgneW • CWE-20: Improper Input Validation •
