https://notcve.org/view.php?id=CVE-2017-6297

The L2TP Client in MikroTik RouterOS versions 6.83.3 and 6.37.4 does not enable IPsec encryption after a reboot, which allows man-in-the-middle attackers to view transmitted data unencrypted and gain access to networks on the L2TP server by monitoring the packets for the transmitted data and obtaining the L2TP secret. El Cliente L2TP en MikroTik RouterOS versiones 6.83.3 y 6.37.4 no habilita el cifrado IPsec después de un reinicio, lo que permite a atacantes man-in-the-middle ver los datos transmitidos sin cifrar y obtener acceso a las redes en el servidor L2TP monitorizando los paquetes para los datos transmitidos y obtener el secreto L2TP. • http://www.securityfocus.com/bid/96447 https://blog.milne.it/2017/02/24/mikrotik-routeros-security-vulnerability-l2tp-tunnel-unencrypted-cve-2017-6297 • CWE-311: Missing Encryption of Sensitive Data •
