Cisco Catalyst SD-WAN Controller Authenticated Privilege Escalation Vulnerability

CVSS 7.8 HIGHEPSS 9.9%● KEVCWE-116
En resumen

Una falla en los productos Cisco Catalyst SD-WAN (Controller, Manager y Validator) permite que un usuario autenticado con privilegios de administrador ejecute comandos como root enviando un archivo especialmente preparado. Esto otorga al atacante control total del sistema.

Detalle técnico

Validación insuficiente de entrada en el CLI permite que usuarios autenticados con privilegios netadmin ejecuten comandos arbitrarios con privilegios de root mediante carga de archivos e inyección de comandos. La explotación exitosa puede resultar en compromiso del sistema y cambios de configuración no autorizados propagados a dispositivos edge.

Resumen generado y traducido por IA a partir de la descripción oficial.
A vulnerability in the CLI of Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an authenticated, local attacker to execute arbitrary commands as root by supplying a crafted file to the affected system. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to perform command injection attacks on an affected system and elevate their privileges as the root user.  To exploit this vulnerability, the attacker must have netadmin privileges on the affected system. This would require valid credentials or exploitation of or . Cisco is not aware of successful exploitation by other methods. Cisco has observed limited cases where the exploitation of this bug resulted in a configuration change pushed to edge devices. Cisco recommends that customers upgrade to the fixed software that is documented in the that was published on May 14, 2026, and verify the configuration of the edge devices.
