CVSS: 9.0EPSS: 0%CPEs: 142EXPL: 1CVE-2022-20719 – Cisco IOx Application Hosting Environment Vulnerabilities
https://notcve.org/view.php?id=CVE-2022-20719
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el entorno de alojamiento de aplicaciones Cisco IOx en varias plataformas de Cisco podrían permitir a un atacante inyectar comandos arbitrarios en el sistema operativo anfitrión subyacente, ejecutar código arbitrario en el sistema operativo anfitrión subyacente, instalar aplicaciones sin ser autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.

CVSS: 7.8EPSS: 0%CPEs: 115EXPL: 0CVE-2021-1529 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1529
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges. The vulnerability is due to insufficient input validation by the system CLI. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges. Una vulnerabilidad en la CLI de Cisco IOS XE SD-WAN Software podría permitir a un atacante local autenticado ejecutar comandos arbitrarios con privilegios de root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-rhpbE34A • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.4EPSS: 0%CPEs: 49EXPL: 0CVE-2021-1621 – Cisco IOS XE Software Interface Queue Wedge Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1621
A vulnerability in the Layer 2 punt code of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a queue wedge on an interface that receives specific Layer 2 frames, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of certain Layer 2 frames. An attacker could exploit this vulnerability by sending specific Layer 2 frames on the segment the router is connected to. A successful exploit could allow the attacker to cause a queue wedge on the interface, resulting in a DoS condition. Una vulnerabilidad en el código de punt de Capa 2 de Cisco IOS XE Software podría permitir a un atacante adyacente y no autenticado causar una queue wedge en una interfaz que reciba tramas específicas de Capa 2, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-quewedge-69BsHUBW • CWE-399: Resource Management Errors •
CVSS: 7.7EPSS: 0%CPEs: 965EXPL: 0CVE-2021-1620 – Cisco IOS and IOS XE Software IKEv2 AutoReconnect Feature Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1620
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition. Una vulnerabilidad en el soporte de Intercambio de Claves de Internet Versión 2 (IKEv2) para la funcionalidad AutoReconnect de Cisco IOS Software y Cisco IOS XE Software podría permitir a un atacante remoto autenticado agotar las direcciones IP libres del pool local asignado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev2-ebFrwMPr • CWE-563: Assignment to Variable without Use CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 9.8EPSS: 0%CPEs: 264EXPL: 0CVE-2021-1619 – Cisco IOS XE Software NETCONF and RESTCONF Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1619
A vulnerability in the authentication, authorization, and accounting (AAA) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass NETCONF or RESTCONF authentication and do either of the following: Install, manipulate, or delete the configuration of an affected device Cause memory corruption that results in a denial of service (DoS) on an affected device This vulnerability is due to an uninitialized variable. An attacker could exploit this vulnerability by sending a series of NETCONF or RESTCONF requests to an affected device. A successful exploit could allow the attacker to use NETCONF or RESTCONF to install, manipulate, or delete the configuration of a network device or to corrupt memory on the device, resulting a DoS. Una vulnerabilidad en la función de autenticación, autorización y contabilidad (AAA) de Cisco IOS XE Software podría permitir a un atacante remoto no autenticado omitir la autenticación NETCONF o RESTCONF y realizar cualquiera de las siguientes acciones Instalar, manipular o eliminar la configuración de un dispositivo afectado. Causar una corrupción de la memoria que resulte en una denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aaa-Yx47ZT8Q • CWE-824: Access of Uninitialized Pointer CWE-908: Use of Uninitialized Resource •
