Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In OPCFoundation.NetStandard.Opc.Ua.Core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A buffer-management vulnerability in OPC Foundation OPCFoundation.NetStandard.Opc.Ua.Core before 1.5.374.54 could allow remote attackers to exhaust memory resources. It is triggered when the system receives an excessive number of messages from a remote source. This could potentially lead to a denial of service (DoS) condition, disrupting the normal operation of the system.
