Denial-of-service vulnerability in the web server of the Eaton SMP Gateway allows
attacker to potentially force an unexpected restart of the automation platform, impacting the availability of the product. In rare situations, the issue could cause the SMP device to restart in Safe Mode or Max Safe Mode. When in Max Safe Mode, the product is not vulnerable anymore.
The product does not properly control the allocation and maintenance of a limited resource.

Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
