CVE-2020-7474

Code execution via project-file DLL search path

Published Mar 23, 2020 · Updated Aug 4, 2024

Uncontrolled DLL search in Schneider Electric ProSoft Configurator 1.002 and earlier allows attackers to execute code via a project file. When a user double-clicks a crafted project file, the application searches an attacker-influenced location and loads a malicious DLL. Exploitation requires local access and user interaction and runs the DLL with the privileges of the user who opens the project.
