CVE-2025-40820siemenssidoor_atd430w_firmware+144
EPSS score0.49%
Affected products do not properly enforce TCP sequence number validation in specific scenarios but accept values within a broad range. This could allow an unauthenticated remote attacker e.g. to interfere with connection setup, potentially leading to a denial of service. The attack succeeds only if an attacker can inject IP packets with spoofed addresses at precisely timed moments, and it affects only TCP-based services.CVE-2024-23814siemenssidoor_atd430w_firmware+136EPSS score0.62%
The integrated ICMP service of the network stack of affected devices can be forced to exhaust its available memory resources when receiving specially crafted messages targeting IP fragment re-assembly. This could allow an unauthenticated remote attacker to cause a temporary denial of service condition of the ICMP service, other communication services are not affected. Affected devices will resume normal operation after the attack terminates.
