      "value": "Sparx Enterprise Architect software has a security feature that limits user's actions to those specified in the role. An authenticated attacker can modify the Enterprise Architect  client behavior (e.g. using a debugger) and log in as any other user or administrator - then it is possible to do every possible change to the repository.\n\nThe vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 17.1 and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable."

      "value": "El software Sparx Enterprise Architect tiene una característica de seguridad que limita las acciones del usuario a las especificadas en el rol. Un atacante autenticado puede modificar el comportamiento del cliente de Enterprise Architect (p. ej., usando un depurador) e iniciar sesión como cualquier otro usuario o administrador; entonces es posible realizar cualquier cambio posible en el repositorio.\n\nSe notificó al proveedor con antelación sobre esta vulnerabilidad, pero no respondió con los detalles de la vulnerabilidad o el rango de versiones vulnerables. Solo la versión 17.1 e inferiores fueron probadas y confirmadas como vulnerables; otras versiones no fueron probadas y también podrían ser vulnerables."
