Tor Browser Fixes Vulnerability That Tracks You Using Installed Apps

Tor Browser Fixes Vulnerability That Tracks You Using Installed Apps

The Tor Project has released Tor Browser 10.0.18 to fix numerous bugs, including a vulnerability that allows sites to track users by fingerprinting the applications installed on their devices.

In May, JavaScript fingerprinting firm FingerprintJS disclosed a ‘scheme flooding’ vulnerability that allows the tracking of users across different browsers based on the applications installed on their device.

To track users, a tracking profile is created for a user by attempting to open various application URL handlers, such as zoommtg://, and checking if the browser launches a prompt, like the one for Zoom below.

If the application’s prompt is displayed, it can be assumed that the application is installed on the device. By checking for numerous URL handlers, the vulnerability can create an ID based on the unique configuration of installed apps on the user’s device.

This ID can then be tracked across different browsers, including Google Chrome, Edge, Tor Browser, Firefox, and Safari.

This vulnerability is especially concerning for Tor users who use the browser to protect their identity and IP address from being logged with sites. As this vulnerability tracks users across browsers, it could allow web sites, and even law enforcement, to track a user’s real IP address when they switch to a non-anonymizing browser, such as Google Chrome.

With the release of Tor Browser 10.0.18, the Tor Project has introduced a fix for this vulnerability by setting the ‘network.protocol-handler.external’ setting to false.

This default setting will prevent the browser from passing the handling of a particular URL to an external application and thus no longer trigger the application prompts.
