Gesytec Easylon OPC Server fails to properly validate OPC server handles
The Gesytec Easylon OPC Server contains a vulnerability that may allow a remote attacker to execute arbitary code or cause a denial-of-service condition.
OLE for Process Control (OPC) is a specification for a standard set of OLE COM objects used in the process control and manufacturing fields. OPC servers are often used in control systems to consolidate field and network device information.
The Gesytec Easylon 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 Gesytec Easylon 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.
Gesytec has released version 2.3.44 of the Easylon OPC server to correct this vulnerability.
