| CVE-2020-8867 | 1 Opcfoundation | 1 Unified Architecture .net-standard | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of OPC Foundation UA .NET Standard 1.04.358.30. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of sessions. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to create a denial-of-service condition against the application.
