Delta Electronics DVP12SE PLC
View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to remotely issue commands, modify operational values, interfere with control logic, and alter device behavior without authentication or privilege enforcement. The following versions of Delta Electronics DVP12SE PLC are affected: DVP12SE PLC vers:all/* (CVE-2026-12819, CVE-2026-12818) CVSS Vendor Equipment Vulnerabilities v3 9.8 Delta Electronics Delta Electronics DVP12SE PLC Missing Authentication for Critical Function, Allocation of Resources Without Limits or Throttling Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Taiwan Vulnerabilities Expand All + CVE-2026-12819 The Delta Electronics DVP12SE PLC exposes a Modbus TCP service over a specified port without authentication or access control, permitting unauthenticated interaction with security-sensitive PLC functions. The device accepts Modbus commands from any reachable network source without requiring credentials, privilege validation, or operator approval, allowing unauthorized read and write access to coils, holding registers, operational memory, relay states, and process control functions.
