CVE-2024-33862

Name of the Vulnerable Software and Affected Versions OPC Foundation OPCFoundation.NetStandard.Opc.Ua.Core versions prior to 1.05.374.54

Description A buffer-management issue could allow remote attackers to exhaust memory resources by sending an excessive number of messages from a remote source, potentially leading to a denial of service (DoS) condition and disrupting the normal operation of the system.

Recommendations For versions prior to 1.05.374.54, update to version 1.05.374.54 or later to resolve the issue. As a temporary workaround, consider implementing rate limiting on incoming messages to minimize the risk of exploitation. Restrict access to the system from untrusted sources to reduce the likelihood of a denial of service (DoS) condition.
