Failure to validate certificates in OPC Foundation UA Client Applications communicating without security allows attackers with control over a piece of network infrastructure to decrypt passwords.CVE-2021-40142opcfoundationlocal_discover_server+6EPSS score2.56%
In OPC Foundation Local Discovery Server (LDS) before 1.04.402.463, remote attackers can cause a denial of service (DoS) by sending carefully crafted messages that lead to Access of a Memory Location After the End of a Buffer.CVE-2021-27432opcfoundationua_.net_standard_stack+1EPSS score1.95%
OPC Foundation UA .NET Standard versions prior to 1.4.365.48 and OPC UA .NET Legacy are vulnerable to an uncontrolled recursion, which may allow an attacker to trigger a stack overflow.CVE-2021-45117opcfoundationua-nodeset+3EPSS score1.42%
The OPC autogenerated ANSI C stack stubs (in the NodeSets) do not handle all error cases. This can lead to a NULL pointer dereference.CVE-2020-29457NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score0.31%
A Privilege Elevation vulnerability in OPC UA .NET Standard Stack 1.4.363.107 could allow a rogue application to establish a secure connection.CVE-2020-8867NuGetOPCFoundation.NetStandard.Opc.Ua+2EPSS score2.64%
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. Was ZDI-CAN-10295.CVE-2022-29866NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score1.68%
OPC UA .NET Standard Stack 1.04.368 allows a remote attacker to exhaust the memory resources of a server via a crafted request that triggers Uncontrolled Resource Consumption.CVE-2022-29863NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score1.46%
OPC UA .NET Standard Stack 1.04.368 allows remote attacker to cause a crash via a crafted message that triggers excessive memory allocation.CVE-2022-29862NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score1.68%
An infinite loop in OPC UA .NET Standard Stack 1.04.368 allows a remote attackers to cause the application to hang via a crafted message.CVE-2022-29865NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score1.62%
OPC UA .NET Standard Stack allows a remote attacker to bypass the application authentication check via crafted fake credentials.CVE-2022-29864NuGetOPCFoundation.NetStandard.Opc.Ua.Core+1EPSS score1.99%
OPC UA .NET Standard Stack 1.04.368 allows a remote attacker to cause a server to crash via a large number of messages that trigger Uncontrolled Resource Consumption.CVE-2022-44725opcfoundationlocal_discovery_serverEPSS score0.18%
OPC Foundation Local Discovery Server (LDS) through 1.04.403.478 uses a hard-coded file path to a configuration file. This allows a normal user to create a malicious file that is loaded by LDS (running as a high-privilege user).CVE-2022-30551opcfoundationua-javaEPSS score2.09%
OPC UA Legacy Java Stack 2022-04-01 allows a remote attacker to cause a server to stop processing messages by sending crafted messages that exhaust available resources.CVE-2022-33916NuGetOPCFoundation.NetStandard.Opc.Ua.Server+1EPSS score1.39%
OPC UA .NET Standard Reference Server 1.04.368 allows a remote attacker to cause the application to access sensitive information.CVE-2017-11672opcfoundationlocal_discovery_serverEPSS score0.32%
The OPC Foundation Local Discovery Server (LDS) before 1.03.367 is installed as a Windows Service without adding double quotes around the opcualds.exe executable path, which might allow local users to gain privileges.CVE-2017-17443opcfoundationlocal_discovery_serverEPSS score0.90%
OPC Foundation Local Discovery Server (LDS) 1.03.370 required a security update to resolve multiple vulnerabilities that allow attackers to trigger a crash by placing invalid data into the configuration file. This vulnerability requires an attacker with access to the file system where the configuration file is stored; however, if the configuration file is altered the LDS will be unavailable until it is repaired.CVE-2017-12070opcfoundationua-.net-legacyEPSS score1.03%
