TITLE

MikroTik RouterOS of L2TP Vulnerability to view unencrypted transmission data on the client

Trust: 0.8

sources: JVNDB: JVNDB-2017-002233

DESCRIPTION

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. MikroTik RouterOS is a routing operating system based on the Linux kernel. MikroTik RouterOS is prone to a security-bypass vulnerability. Successfully exploiting this issue may allow attackers to perform unauthorized actions by conducting a man-in-the-middle attack. This may lead to other attacks. RouterOS 6.83.3 and 6.37.4 are vulnerable; other versions may also be affected. This system turns a PC computer into a professional router. L2TP Client is one of the communication protocol clients
