Description

CVE-2020-24367

Bluestacks 4 is vulnerable to privilege escalation attacks that allow a local user on Windows
(“Low Integrity”) to induce the execution of code with administrative scope ("High Integrity") on
Windows 10. This is due to incorrect permissions set by Bluestacks when installed, which
allows any user (“Everyone”) to modify files that may later be executed with administrative
privileges.
