An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could allow the attacker to cause the vDaemon listening service to reload and result in a DoS condition.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability."},{"lang":"es","value":"Una vulnerabilidad en el servicio vDaemon de Cisco SD-WAN vManage Software podría permitir que un atacante local autenticado provoque un desbordamiento de búfer en un sistema afectado, lo que daría como resultado una condición de denegación de servicio (DoS). La vulnerabilidad se debe a comprobaciones de los límites incompletas para los datos que se proporcionan al servicio vDaemon de un sistema afectado. Un atacante podría aprovechar esta vulnerabilidad enviando datos maliciosos al servicio de escucha vDaemon en el sistema afectado. Una explotación exitosa podría permitir que el atacante provoque una condición de desbordamiento de búfer en el sistema afectado, lo que podría permitirle al atacante hacer que el servicio de escucha vDaemon se vuelva a cargar y genere una condición de denegación de servicio (DoS). Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad.
