Description
A remote unprivileged attacker can sent multiple packages to the LMS5xx to disrupt its availability through a TCP SYN-based denial-of-service (DDoS) attack.
By exploiting this vulnerability, an attacker can flood the targeted LMS5xx with a high volume of TCP SYN requests, overwhelming its resources and causing it to become unresponsive or unavailable for legitimate users.
