This vulnerability occurs when an ActiveX control designed for limited use is incorrectly flagged as safe for scripting, allowing web pages to access its potentially dangerous functions.
ActiveX controls are reusable software components, but some contain functionality that should only run in trusted environments. When developers or packagers mistakenly mark a restricted control as 'safe for scripting,' they remove the browser's security barrier that normally blocks untrusted web pages from interacting with it. This misconfiguration lets attackers embed malicious scripts in web pages that call the control's dangerous methods. Depending on what the control can do, this could lead to data theft, system takeover, or other exploits—effectively turning a legitimate component into an attack vector through a simple marking error.
