CVE-2019-20769

Local code execution via current-directory DLL loading

Published Apr 17, 2020 · Updated Aug 5, 2024

DLL hijacking in LG PC Suite 5.3.27 and earlier allows local users to execute arbitrary code through a Trojan horse DLL. The application searches the current working directory for a DLL and loads an attacker-controlled library without constraining the lookup to a trusted path. Exploitation requires user interaction and placement of the crafted DLL in that directory; the loaded code runs with the application's privileges.
