Attack-Flow Graph

Executive Summary

This vulnerability occurs in Firefox for iOS versions before 147.2.1, where malicious scripts can interrupt the loading of new tab pages. This interruption causes a desynchronization between the address bar and the actual page content.

As a result, an attacker can spoof arbitrary HTML content under a trusted domain, meaning the address bar shows a legitimate URL while the page content is fraudulent.

Impact Analysis

The vulnerability can mislead users by displaying fraudulent web pages while showing legitimate URLs in the address bar.

This can enable attackers to conduct website spoofing attacks, potentially tricking users into divulging sensitive information or performing unintended actions.
