Currently unrated
What is CVE-2025-56234?
The AT_NA2000 PLC from Nanda Automation Technology exhibits a vulnerability in its handling of TCP RST packets. It allows for a wide range of acceptable sequence numbers, deviating from the requirements outlined in RFC5961. As a consequence, attackers can exploit this flaw by sending arbitrary TCP RST packets within the acceptable range. This exploitation can lead to significant interruptions in network connections, resulting in a denial-of-service scenario that disrupts normal operational capabilities.
