What is CVE-2024-5000?

The vulnerability arises from a flaw in the handling of requests sent by an unauthenticated remote attacker using a malicious OPC UA client. When the crafted request is processed, it can trigger a denial of service (DoS) condition due to improper buffer size calculations within the affected CODESYS products. This can lead to service disruptions and impact the operational integrity of systems relying on the CODESYS Automation Platform.
