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

Vulnerability from cvelistv5 – Published: 2017-02-27 07:25 – Updated: 2024-08-05 15:25

Summary

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.

Severity ?

No CVSS data available.
