This security update resolves a vulnerability in the OPC UA .NET Standard Stack that allows an unauthorized attacker to bypass application authentication when the deprecated Basic128Rsa15 security policy is enabled. Note that the Basic128Rsa15 is disabled by default so most users will not be affected. When this patch is applied the Server closes all channels using the Basic128Rsa15 if an attack is detected. This introduces a DoS before any compromise can occur which is preferable to a compromise. To prevent this failure, applications must stop using Basic128Rsa15.
Recommended action: Upgrade to 1.5.374.158 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
This security update resolves a vulnerability in the OPC UA .NET Standard Stack that allows an unauthorized attacker to trigger a gradual degradation in performance.
Recommended action: Upgrade to 1.5.374.118 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
This security update resolves a vulnerability in the OPC UA .NET Standard Stack that enables an unauthorized attacker to trigger a rapid increase in memory consumption.
Recommended action: Upgrade to 1.05.374.54 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
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.
Recommended action: Upgrade to 1.5.374.54 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
This security update resolves a vulnerability in the OPC UA .NET Standard Reference Server that allows remote attackers to send malicious requests that expose sensitive information. https://files.opcfoundation.org/SecurityBulletins/OPC%20Foundation%20Security%20Bulletin%20CVE-2023-31048.pdf
Recommended action: Upgrade to 1.4.371.86 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
