FAQ

According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution? This attack requires a specially crafted file to be placed either in an online directory or in a local network location. When a victim runs this file, it loads the malicious DLL. How could an attacker exploit this vulnerability? An unauthenticated attacker could exploit the vulnerability by placing a specially crafted file onto an online directory or in a local network location then convincing the user to open it. In a successful attack, this will then load a malicious DLL which could lead to a remote code execution.
