CVE-2017-6297 (GCVE-0-2017-6297)

Vulnerability from cvelistv5 – Published: 2017-02-27 07:25 – Updated: 2026-09-16 20:45

Summary

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.

Severity

No CVSS data available.
