CVE-2026-19586
Full vulnerability record from the local CVENow database.
Description
A pre-authentication OS command injection vulnerability has been identified in Omada gateways configured to operate as an OpenVPN Server due to insufficient validation of client-supplied data during OpenVPN connection establishment. An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt. Successful exploitation may allow arbitrary command execution, potentially leading to full compromise of the affected device.

"value": "Una vulnerabilidad de inyección de comandos del sistema operativo pre-autenticación ha sido identificada en gateways Omada configurados para operar como un servidor OpenVPN debido a una validación insuficiente de los datos proporcionados por el cliente durante el establecimiento de la conexión OpenVPN. Un atacante remoto no autenticado puede proporcionar una entrada especialmente diseñada que influye en la lógica de ejecución de comandos del backend antes de que la autenticación se complete. La explotación requiere que la característica de servidor OpenVPN esté habilitada, que el servicio VPN sea accesible por el atacante y que el atacante pueda iniciar un intento de conexión OpenVPN.\n\nLa explotación exitosa puede permitir la ejecución arbitraria de comandos, lo que podría llevar a un compromiso total del dispositivo afectado."
