3 vulnerabilities found for OPC Drivers by IOServer
VAR-201404-0549
Vulnerability from variot - Updated: 2023-12-18 13:14The Modbus slave/outstation driver in the OPC Drivers 1.0.20 and earlier in IOServer OPC Server allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted packet. IOServer is a Windows-based OPC server that allows OPC clients such as human-machine interfaces and monitoring and data acquisition systems to exchange factory data with programmable logic circuits. IOServer is prone to an out-of-bounds read vulnerability. OPC Drivers versions prior to 1.0.20 are vulnerable
