# CVE-2017-6297

> 3.1 LOW

## Beschreibung

The L2TP Client in MikroTik RouterOS versions 6.38.3 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.
