CVE-2022-20677 – Cisco IOx Application Hosting Environment Vulnerabilities
https://notcve.org/view.php?id=CVE-2022-20677
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 del host subyacente, ejecutar código arbitrario en el sistema operativo del host subyacente, instalar aplicaciones sin estar autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.

CVE-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 •
CVE-2021-1452 – Cisco IOS XE ROM Monitor Software for Cisco Industrial Switches OS Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1452
A vulnerability in the ROM Monitor (ROMMON) of Cisco IOS XE Software for Cisco Catalyst IE3200, IE3300, and IE3400 Rugged Series Switches, Cisco Catalyst IE3400 Heavy Duty Series Switches, and Cisco Embedded Services 3300 Series Switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. This vulnerability is due to incorrect validations of specific function arguments passed to a boot script when specific ROMMON variables are set. An attacker could exploit this vulnerability by setting malicious values for a specific ROMMON variable. A successful exploit could allow the attacker to execute unsigned code and bypass the image verification check during the secure boot process of an affected device. To exploit this vulnerability, the attacker would need to have unauthenticated, physical access to the device or obtain privileged access to the root shell on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-romvar-cmd-inj-N56fYbrw • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
