To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted IPC message to the AnyConnect process on an affected device. A successful exploit could allow the attacker to stop the AnyConnect process, causing a DoS condition on the device. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system."},{"lang":"es","value":"Una vulnerabilidad en el canal de comunicación entre procesos (IPC) de Cisco AnyConnect Secure Mobility Client para Windows podría permitir a un atacante local autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. Para explotar esta vulnerabilidad, el atacante podría necesitar credenciales válidas en el sistema Windows. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de un mensaje IPC diseñado al proceso AnyConnect sobre un dispositivo afectado. Una explotación con éxito podría permitir al atacante detener el proceso AnyConnect, causando una condición DoS en el dispositivo.
