Name of the Vulnerable Software and Affected Versions MikroTik Router hAP Lite version 6.25

Description The issue allows remote attackers to cause a denial of service by sending many unsolicited TCP ACK packets, resulting in high CPU consumption. After the attack stops, the CPU usage remains at 100%, and the router requires a reboot to resume normal operation.

Recommendations For version 6.25, consider restricting access to the network to minimize the risk of exploitation until a patch is available. As a temporary workaround, monitor CPU usage and be prepared to reboot the router in case of an attack. At the moment, there is no information about a newer version that contains a fix for this issue.
