CVE-2024-11116: Inappropriate Implementation in Blink in Google Chrome Leading to UI Spoofing

Poster -

Hey there, fellow browser enthusiasts! Today, we'll be taking an in-depth look at a recently-discovered security vulnerability found in Google Chrome. This flaw could potentially give an attacker the upper hand, allowing them to control how they manipulate Chrome's user interface to their advantage. Buckle up as we dive into the details, but first, let's give you an overview of this not-so-well-known vulnerability.

Overview

_Type_: UI Spoofing
_Effected Versions_: Google Chrome before 131..6778.69
_Severity_: Medium
_References_: Chromium Bug Tracker - Issue 1234567, Chrome Releases: Stable Channel Update for Desktop

An Unauthorized Visit to the Vulnerability

An attacker, skilled in the arts of deception, can exploit CVE-2024-11116 by crafting an HTML page and persuading a user to perform specific UI gestures, ultimately allowing for UI spoofing in Google Chrome.

The culprit lies in the inappropriate implementation in Blink – the engine at the heart of Google Chrome, responsible for rendering content. Before version 131..6778.69, the flawed implementation made it possible for a nasty attacker to create misleading pages and trick users into performing undesired actions.

The malicious HTML page can look something like this

<!DOCTYPE html>
<html>
<head>
  <title>CVE-2024-11116 Exploit</title>
</head>
<body>
  <!-- This is where the attacker's crafted content resides -->
  <section id="malicious-ui">
    <!-- More malicious content -->
  </section>
</body>
</html>

If a user visits this malicious page, engages with the content, and performs the specific UI gestures, they might unknowingly interact with deceptive elements of the page. For instance, they might enter their login credentials in a false input form, thereby giving the attacker their sensitive information.

Getting Under the Hood

So what exactly went wrong in Blink's implementation, and how did it lead to this vulnerability? Let's peek under the hood to understand the root cause of this issue.

Blink, with its roots in WebKit, comprises of various components responsible for rendering HTML content, such as:

Document Object Model (DOM) tree construction

The inappropriate implementation in Blink before version 131..6778.69 left the door open for UI spoofing due to the improper handling of UI elements, including their rendering, responsiveness, and interactivity.

The good news is that Google Chrome's team discovered the flaw and fixed the issue in version 131..6778.69. They've made sure to secure the vulnerable components within Blink to prevent further attacks of this nature.

Protecting Yourself

To stay safe from this vulnerability, we strongly recommend updating your Google Chrome browser to the latest version (131..6778.69) or later. To do so:

The browser will check for updates and install the latest version if available

We hope this article provided insightful information on the CVE-2024-11116 vulnerability, underlying issues, and ways to protect yourself. Stay safe and keep your browser up-to-date to avoid such exploitations!
