Problem Statement

Our users often get hacked via vulnerable third party plug-ins.

Proposal

Create a service anybody can use on any site to increase plugin awareness for their users.

Components

Tracker bug: bug 465898

  • Create database to store plugin information bug 465888
  • Plugins service to serve plugin metadata via XML or JSON bug 465891
  • Create javascript library for embedding bug 465891

mozilla.com areas of influence:

  • Firstrun page
  • What's new page
  • Upyourplug page

Landing pages

First Run

FIRST RUN p2ALT MAC.jpg

Add an alert that checks the first time a user opens Firefox:

Message: We detected that some of your media plug-ins are vulnerable, click here for more info.

This is non-invasive, as we do not want to have the user have trouble getting started with Firefox.

This will lead the user to the plug-in check page.

comment [morgamic] -- please eliminate the "click here". A "more info" that is a hyperlink should be sufficient. "click here" is bad wording for a hyperlink because it's non-descriptive. When I was messing with it, "Update your plug-ins." seemed even better -- but just pick something besides "click here".  :)

comment clouserw -- "vulnerable" is a pretty strong word. Are we actually detecting that they are using versions that are vulnerable, or just that they are using outdated versions?

comment polvi -- The goal is to detect vulnerable plug-ins, not outdated ones (although, they often go hand in hand). Regarding "click here", I agree, but we are trying to structure the language such that it avoids demanding something of the user.

Updated

Add similar alert to the "you've been updated" page which leads to the plug-in check page.

Implementation

It will be easiest to check the basic functionality in Javascript. Bug 282258 has a script that should work for flash and java.

UpYourPlug page

This page will do a check on common plug-ins and see if they are vulnerable or not. An example implementation can be found here.

Plug-ins to check:

  • Java (system update)
  • Flash (provides API, system update)

Future plug-ins to check:

  • Windows media player (system update)
  • Real player (system update)
  • Quicktime (system update)

Mock-up

Here is a cheesy mock-up of the idea for the plug-in update check page.

Implementation

The actual checks need to be implemented in javascript. The following use cases should be handled accordingly:

  • Plugin installed and up to date: An green "OK" box displayed linked to vendor
  • Plugin installed and out of date: A red "need update" box displayed linked to vendor
  • Plugin not installed: A gray "not installed" box displayed.

Java on the Mac

Since only the java embedding plugin gives version information to javascript, we cannot check for this case without a java applet. In this case, display a gray "check with vendor" box that links to Sun's java plugin page.

Non-Firefox Browsers

If a non Firefox browser hits this page, we need to display a notice with the rest of the copy on the page: "This page is only supported when using Firefox". Then all the checks should be a gray "check with vendor" box that link accordingly.

Determining the latest secure version

Ideally we would talk to the upstream provider and get the latest secure version. However, initially we can just maintain a file that includes the latest versions of the plug-ins.

We found an insecure plug-in, now what?

After we detect that a plug-in is out of date, we should open the vendor page in a new tab.

One major concern is that each plug-in update needs a browser restart.

Java

Sun provides an update check. Linking here should provide a sufficient starting point for getting java up to date.

Flash

Adobe provides an update check. The user will be offered to navigate to this page for the update.

Schedule

A rough timeline...

First run revamp launch ~ August 24th

Finish UpYourPlug page ~ August 24th

Launch page and add detection to first run page - August 31th

Add detection to updated page - September 7th

Postmortem

  • be more specific about copy wording and mock-up layout
  • note when the alerts should display
  • s/sans/without/
  • think of edge cases ahead of time if possible
  • talk about projects like this at start of quarters to get a better response
