openplc v3

About this tag
OpenPLC v3 is an open-source programmable logic controller runtime that runs on Windows and other platforms. Recent discussions on WindowsForum.com highlight two critical security vulnerabilities affecting OpenPLC v3. The first is a Cross-Site Request Forgery (CSRF) flaw in the web interface, which could allow an unauthenticated attacker to trick an authenticated administrator into changing PLC configuration or uploading programs. The second is a denial-of-service (DoS) bug in the EtherNet/IP thread (enipThread) that can crash the PLC runtime, causing operational downtime. Both issues have vendor-provided fixes via pull requests. Operators using OpenPLC v3 on Windows should apply these patches urgently to maintain security and reliability.
