      "value": "Improper Handling of Syntactically Invalid Structure in Sparx Pro Cloud Server allows Denial of Service (DoS) attack to be executed by sending an specially crafted SQL query. This causes the Pro Cloud Server service to terminate unexpectedly. \n\nThe vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable."

      "value": "El manejo inadecuado de una estructura sintácticamente inválida en Sparx Pro Cloud Server permite que se ejecute un ataque de denegación de servicio (DoS) al enviar una consulta SQL especialmente diseñada. Esto provoca que el servicio de Pro Cloud Server termine inesperadamente. Se notificó al proveedor con antelación sobre esta vulnerabilidad, pero no respondió con los detalles de la vulnerabilidad ni el rango de versiones vulnerables. Solo la versión 6.1 (compilación 167) e inferiores fueron probadas y confirmadas como vulnerables; otras versiones no fueron probadas y también podrían ser vulnerables."
