What are the conditions under which the CVE-2017-8464 vulnerability can be triggered?

The vulnerability can be triggered in three main scenarios: (1) when the system has USB AutoPlay enabled and a malicious USB drive is inserted, (2) when the user accesses a network share containing a malicious .lnk file, or (3) when the user directly browses to a directory with the crafted shortcut. No user interaction beyond these actions is required to exploit the flaw. This is explained in detail in the Exploitation Testing of Windows Lnk Remote Code Execution Vulnerability (CVE-2017-8464) article.
