The NETxAutomation NETxEIB OPC Server contains a vulnerability that may allow a remote attacker to execute arbitary code or cause a denial-of-service.
OLE for Process Control (OPC) is a specification for a standard set of OLE COM objects for use in the process control and manufacturing fields. OPC servers are often used in control systems to consolidate field and network device information.
The NETxAutomation NETxEIB OPC Server fails to properly validate server handles. This vulnerability may be triggered by an attacker with access to the server's OPC interface.
An attacker with access to the NETxEIB OPC Server may be able to arbitrarily access server process memory, potentially allowing that attacker to execute arbitrary code or cause a denial-of-service.
