What is CVE-2020-15264?
CVE-2020-15264 is a high-severity vulnerability in chocolatey boxstarter, published on 20 Oct 2020. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
The Boxstarter installer before version 2.13.0 configures C:\ProgramData\Boxstarter to be in the system-wide PATH environment variable. However, this directory is writable by normal, unprivileged users. To exploit the vulnerability, place a DLL in this directory that a privileged service is looking for. For example, WptsExtensions.dll When Windows starts, it'll execute the code in DllMain() with SYSTEM privileges. Any unprivileged user can execute code with SYSTEM privileges. The issue is fixed in version 3.13.0
