CVE-2022-20829
Cisco Adaptive Security Device Manager and Adaptive Security Appliance Software Client-side Arbitrary Code Execution Vulnerability
En resumen
Una falla en los firewalls Cisco ASA permite que un administrador malicioso cargue una interfaz de gestión falsificada (ASDM) que engaña a los usuarios para ejecutar código dañino en sus computadoras. Esto es crítico porque compromete a cualquiera que administre el firewall de forma remota.
Detalle técnico
La validación insuficiente de la autenticidad de la imagen ASDM durante la instalación en dispositivos Cisco ASA permite que un atacante remoto autenticado con privilegios administrativos cargue un paquete ASDM manipulado que contiene código malicioso. Cuando un usuario objetivo accede al dispositivo comprometido a través del cliente ASDM, se produce la ejecución de código arbitrario con los privilegios del usuario en la máquina del cliente. La explotación requiere acceso de administrador al dispositivo ASA y se dirige a usuarios ASDM que administran ese dispositivo específico.
Resumen generado y traducido por IA a partir de la descripción oficial.
A vulnerability in the packaging of Cisco Adaptive Security Device Manager (ASDM) images and the validation of those images by Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker with administrative privileges to upload an ASDM image that contains malicious code to a device that is running Cisco ASA Software. This vulnerability is due to insufficient validation of the authenticity of an ASDM image during its installation on a device that is running Cisco ASA Software. An attacker could exploit this vulnerability by installing a crafted ASDM image on the device that is running Cisco ASA Software and then waiting for a targeted user to access that device using ASDM. A successful exploit could allow the attacker to execute arbitrary code on the machine of the targeted user with the privileges of that user on that machine. Notes: To successfully exploit this vulnerability, the attacker must have administrative privileges on the device that is running Cisco ASA Software. Potential targets are limited to users who manage the same device that is running Cisco ASA Software using ASDM. Cisco has released and will release software updates that address this vulnerability.
