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.

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Title: Cisco Catalyst SD-WAN Manager, Description: Una vulnerabilidad en la CLI de Cisco Catalyst SD-WAN Manager, anteriormente SD-WAN vManage, podría permitir a un atacante local y autenticado ejecutar comandos arbitrarios como root al proporcionar un archivo manipulado al sistema afectado.
Esta vulnerabilidad se debe a una validación insuficiente de la entrada proporcionada por el usuario. Un atacante podría explotar esta vulnerabilidad al cargar un archivo manipulado al sistema afectado. Un exploit exitoso podría permitir al atacante realizar ataques de inyección de comandos en un sistema afectado y elevar sus privilegios como usuario root.
Para explotar esta vulnerabilidad, el atacante debe tener privilegios de netadmin en el sistema afectado. Esto requeriría credenciales válidas o la explotación de o . Cisco no tiene conocimiento de explotación exitosa por otros métodos. Cisco ha observado casos limitados en los que la explotación de este error resultó en un cambio de configuración enviado a los dispositivos de borde.
Cisco recomienda que los clientes actualicen al software corregido que está documentado en el que se publicó el 14 de mayo de 2026, y verifiquen la configuración de los dispositivos de borde.
