VAR-201204-0097

Vulnerability from variot - Updated: 2025-04-11 23:02

Open Automation Software OPC Systems.NET before 5.0 allows remote attackers to cause a denial of service via a malformed .NET RPC packet on TCP port 58723. OPC Systems.NET is a .NET product for SCADA, HMI and production line-to-business solutions. OPC Systems.NET handles malformed .NET RPC messages with security vulnerabilities. Submitting malicious requests can cause OPCSystemsService.exe to consume a large amount of CPU, causing denial of service attacks. OPC Systems.NET is prone to a denial-of-service vulnerability. An attacker may exploit this issue to crash the affected application, denying service to legitimate users. OPC Systems.NET 4.00.0048 is vulnerable; other versions may also be affected
