Restricted Javascript in IDE object help files

Overview

A registry-based mechanism to disable or enable Javascript in the System Platform IDE's object help editor has been introduced in this release. It is designed to strengthen system security by disabling Javascript in the html-based object help files by default. This mechanism aims to minimize the risk of malicious or unintended Javascript from being loaded.

By default, Javascript is disabled.

Configuration

You can enable or disable Javascript in the object help editor by editing the relevant registry key. This key is generated during installation and has a default value of 0 (Javascript is disabled).

• Registry Key location: HKEY_LOCAL_MACHINE\SOFTWARE\AVEVA\SystemPlatform\Security

• Value Name: EnableJavaScriptInHelpDialog

• Type: DWORD (0 = Disabled, 1 = Enabled)

Values:

• 0x00000000 (0): Javascript in the object help editor is disabled (default)

• 0x00000001 (1): Javascript in the object help editor is enabled

If the value is not specified, or if the value is anything other 1, Javascript is disabled.
