CVE-2017-6444 (GCVE-0-2017-6444)

Vulnerability from cvelistv5 – Published: 2017-03-12 04:57 – Updated: 2024-08-05 15:33

Summary

The MikroTik Router hAP Lite 6.25 has no protection mechanism for unsolicited TCP ACK packets in the case of a fast network connection, which allows remote attackers to cause a denial of service (CPU consumption) by sending many ACK packets. After the attacker stops the exploit, the CPU usage is 100% and the router requires a reboot for normal operation.

Severity ?

No CVSS data available.
