CVE-2020-25182

Local code execution via uncontrolled DLL loading

Published Mar 18, 2022 · Updated Apr 16, 2025

Uncontrolled DLL loading in Rockwell Automation ISaGRAF Runtime 4.x and 5.x allows local users to execute arbitrary code on Windows. The runtime searches an affected software directory and loads a matching DLL without constraining the search path, so a planted library is executed. Exploitation requires write access to the VirtualStore folder; the flaw is confined to Windows deployments and runs code with the runtime's privileges.
