      "value": "An issue was discovered in vsDesk v14.0101. An authenticated attacker with administrative privileges can bypass client-side file validation in the \"Import via CSV\" component due to a lack of server-side validation. This allows the upload of an arbitrary file, which can lead to Remote Code Execution (RCE) within the context of the web application. \nApply patch from vendor  https://vsdesk.ru/ . Versions 14.0402 and on have the patch."

Un atacante autenticado con privilegios administrativos puede eludir la validación de archivos del lado del cliente en el componente ’Importar vía CSV’ debido a la falta de validación del lado del servidor. Esto permite la carga de un archivo arbitrario, lo que puede conducir a la Ejecución Remota de Código (RCE) dentro del contexto de la aplicación web. Aplique el parche del proveedor https://vsdesk.ru/ . Las versiones 14.0402 y posteriores tienen el parche."
