New: Docker Image as distribution option. Uses Prosys OPC UA SDK for Java version 4.5.2: NOTE! for the "portable install" and docker distributions, there could be more impact if the user running the application differs from the one unzipping the distribution and/or if that user has higher privileges on the system. Thus, this CVE in practice has no impact, but we still do recommend to update just in case. Thus the created configuration files at the first startup are admin-owned, thus there is nothing to escalate to, the attacker could just do already everything they could do via Modbus Server in a more complicated way. Typically this kind of vulnerability could be used for a privilege escalation attack, but Modbus Server for better or worse requires admin priviledges to run. In general our applications do not expect a hostile (local) environment. So the filesystem would have to be compromised for this to happen. These devices are often "wired" through a reliable medium such as Ethernet or serial cables.For the CVE-2021-44832, per apache’s page: "(previous versions) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file". Communication takes place with a PLC, DCS IED, analyzer, or some other controller. Plant Edition: This driver is typically used in manufacturing, batch or process plants. Each read/write with the PLC is optimized to maximize throughput. The Matrikon OPC Server for Modbus PLCs is an OPC compliant server that enables data interchange between OPC clients and Modbus compliant PLCs. This server has been tested with hardware from vendors such as ABB, Emerson, Honeywell, Koyo, Schneider (Modicon), Triconex, Yokogawa, and many others. Each read/write with the devices is optimized to maximize throughput. This server connects to multiple devices using one or more protocols at the same time. The MatrikonOPC Modbus Interface provides connectivity to Modbus compliant devices such as any PLC, RTU, DCS, etc. It is a fully functioning application that can be used for 30 days after which time it must be licensed. The MatrikonOPC Server for Modbus download is shareware that can be distributed freely. ![]() Try the MatrikonOPC Server for Modbus (PLANT EDITION) for FREE now.
