CVE-2025-58456Network attack vector

Arbitrary file read via simulator path traversal

Published Oct 23, 2025 · Updated Oct 23, 2025

Path traversal in AutomationDirect Productivity Suite 4.2.1.9 and earlier allows remote attackers to read arbitrary files without authentication. The ProductivityService PLC simulator resolves attacker-supplied file paths without confining them to the intended directory. Exploitation requires network reachability to the simulator and exposes files on its Windows host, with no reported write or execution capability.
