MikroTik RouterOS Security Vulnerability – L2TP Tunnel Unencrypted – 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. This allows eavesdroppers to view the transmitted data unencrypted. It also allows eavesdroppers to obtain L2TP client secrets and then establish tunnels to the L2TP servers, gaining unauthorised access to the networks they provide access to.
