A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to inject a command to the underlying operating system that will execute with root privileges upon the next reboot of the device. The authenticated user must have privileged EXEC permissions on the device. The vulnerability is due to insufficient protection of values passed to a script that executes during device startup. An attacker could exploit this vulnerability by writing values to a specific file. A successful exploit could allow the attacker to execute commands with root privileges each time the affected device is restarted. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-cmdinj-2MzhjM6K • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

A vulnerability in the persistent Telnet/Secure Shell (SSH) CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges. Una vulnerabilidad en la CLI Telnet/Secure Shell (SSH) persistente de Cisco IOS XE Software, podría permitir a un atacante local autenticado obtener acceso de shell en un dispositivo afectado y ejecutar comandos en el sistema operativo (SO) subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ctbypass-7QHAfHkK • CWE-863: Incorrect Authorization •

A vulnerability in the RESTCONF and NETCONF-YANG access control list (ACL) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of the ACL that is tied to the RESTCONF or NETCONF-YANG feature. An attacker could exploit this vulnerability by accessing the device using RESTCONF or NETCONF-YANG. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la función de lista de control de acceso (ACL) de RESTCONF y NETCONF-YANG de Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar que el dispositivo se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-confacl-HbPtfSuO • CWE-476: NULL Pointer Dereference •

A vulnerability in the Split DNS feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability occurs because the regular expression (regex) engine that is used with the Split DNS feature of affected releases may time out when it processes the DNS name list configuration. An attacker could exploit this vulnerability by trying to resolve an address or hostname that the affected device handles. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad Split DNS de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-splitdns-SPWqpdGW • CWE-185: Incorrect Regular Expression CWE-400: Uncontrolled Resource Consumption •

A vulnerability in Cisco IOS XE Wireless Controller Software for Cisco Catalyst 9800 Series Routers could allow an unauthenticated, adjacent attacker to send ICMPv6 traffic prior to the client being placed into RUN state. The vulnerability is due to an incomplete access control list (ACL) being applied prior to RUN state. An attacker could exploit this vulnerability by connecting to the associated service set identifier (SSID) and sending ICMPv6 traffic. A successful exploit could allow the attacker to send ICMPv6 traffic prior to RUN state. Una vulnerabilidad en Cisco IOS XE Wireless Controller Software para Cisco Catalyst 9800 Series Routers, podría permitir a un atacante adyacente no autenticado enviar tráfico ICMPv6 antes de que el cliente sea ubicado en el estado RUN. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-icmpv6-qb9eYyCR • CWE-284: Improper Access Control •
