"value": "Duo has identified and fixed an issue with the Duo Network Gateway (DNG) product in which some customer-provided SSL certificates and private keys were not excluded from logging. This issue resulted in certificate and private key information being written out in plain-text to local files on the DNG host. Any private keys logged in this way could be viewed by those with access to the DNG host operating system without any need for reversing encrypted values or similar techniques. An attacker that gained access to the DNG logs and with the ability to intercept and manipulate network traffic between a user and the DNG, could decrypt and manipulate SSL/TLS connections to the DNG and to the protected applications behind it. Duo Network Gateway (DNG) versions 1.3.3 through 1.5.7 are affected."

"value": "Duo ha identificado y corregido un problema con el producto Duo Network Gateway (DNG) en el que algunos certificados SSL proporcionados por el cliente y claves privadas no fueron excluidas del registro. Este problema result\u00f3 en que la informaci\u00f3n del certificado y la clave privada ha sido escrita en texto plano para archivos locales en el host DNG. Cualquier clave privada registrada de esta manera podr\u00eda ser visualizada por aquellos con acceso al sistema operativo host DNG sin necesidad de invertir valores cifrados o t\u00e9cnicas similares. Un atacante que consigui\u00f3 acceso a los registros DNG y con la capacidad de interceptar y manipular el tr\u00e1fico de red entre un usuario y el DNG, podr\u00eda descifrar y manipular conexiones SSL/TLS en el DNG y en las aplicaciones protegidas detr\u00e1s de \u00e9l. Duo Network Gateway (DNG) versiones 1.3.3 hasta 1.5.7 est\u00e1n afectadas"
