TITLE

MikroTik Router hAP Lite Service disruption in (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2017-002200

DESCRIPTION

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. MikroTik is a system for developing routers and wireless ISPs. MikroTik Router hAP Lite is a device from Latvian MikroTik company that has dual concurrent access points and provides WiFi coverage for 2.4GHz and 5GHz frequencies simultaneously. A security vulnerability exists in MikroTik Router hAP Lite version 6.25
