Microsoft allows system administrators to disable JScript in Internet Explorer

Microsoft makes it possible for system administrators to disable JScript in Internet Explorer. With a new patch it is possible to disable the JScript component in Internet Explorer 9 and Internet Explorer 11.

The feature is in the October Windows patch earlier this month. In it, it is possible to disable JScript execution in Internet Explorer 9 and 11. System administrators can do this for devices on their network. The JScript component remains active by default, but can be disabled with the url action URLACTION_ALLOW_JSCRIPT _IE. It is also possible to prompt users before enabling the component. The function can be applied to sites located in the Internet Zone or in the Restricted Sites Zone.

JScript is Microsoft’s implementation of JavaScript. The engine was already included in Internet Explorer 3.0 in 1996, and was officially phased out in 2009. However, JScript was still present in Windows. The engine occasionally received security updates, but there were still regular attacks in which JScript was exploited to enable remote code execution.
