New data types include 8 bit and 64 bit integers (SINT, USINT, LINT, ULINT), 64 bit floating-point decimal (LREAL) and character strings encoded in ISO 8859-1 and UTF-16 (CHAR, WCHAR) New: Extended support for different IEC 61131-3 data types. New: Possibility to import and export device-specific variable configurations from/to a CSV file through the Configuration Mode UI
#JAVA MODBUS SERVER SERIAL#
New: Support for Modbus serial protocol (ASCII and RTU) If for some reasons it won’t work on your distro, let us know, but you can chmod the exec bits as a workaround. zip option uncompressed retaining exec bits on start scripts on Linux, which was the only reason keeping tar.gz. Not recommended for public networks.Ĭhanged: Removed portable tar.gz option, based on our latest tests the.

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. 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".
