Permission to upload HTML5 content

Page Overview

[Hide]

1 Initial Problem

As long as not prevented in the Administration of Media Objects and Pools, ILIAS allows to upload HTML5 content as media content. This capability is necessary to embed HTML5-based animations and content in learning content produced with the ILIAS page editor. But it also could be a gateway to infect ILIAS with bad code because everybody with access to the ILIAS page editor (e.g. in portfolios or groups) could upload such infected HTML code. At the time being, a system administrator can only prevent the upload of HTML content as media object in general (for all users). It would be very helpful if the upload of HTML content in media objects could be restricted to a known group of users.

2 Conceptual Summary

ILIAS should be able to control which users are allowed to upload HTML content. This should be done role-based controlled. A local role in the administration of media objects with a related permission should be checked for this.
  1. A new setting "Role-based upload of HTML content" (checkbox) is introduced to 'Administration » Media Objects and Pools'.
  2. A new permission "Upload HTML content" is introduced to the permission node of 'Administration » Media Objects and Pools'.
If the setting "Role-based upload of HTML content" is enabled, the permission "Upload HTML content" will be checked when media objects are uploaded. In case HTML content is uploaded and no permission is given, the upload is prevented and an error message is thrown. The byline for this setting has to explain the impact of this setting. A "reference" of this setting should be added to 'Administration » Privacy and Security : Security', too.
