CVE-2024-11117 - Bypassing FileSystem Restrictions in Google Chrome Prior to 131..6778.69 Using a Crafted HTML Page
A vulnerability with an identifier of CVE-2024-11117 has been discovered affecting Google Chrome versions prior to 131..6778.69. This vulnerability stems from an inappropriate implementation in the FileSystem component and would, if exploited, allow a remote attacker to bypass filesystem restrictions. The attacker could accomplish this by crafting a malicious HTML page to be executed within the target's browser. This vulnerability has been given a "Low" severity rating by the Chromium security team.
Exploit Details
To exploit CVE-2024-11117, an attacker would typically set up a website containing a malicious HTML page. This page would leverage the improper implementation in Google Chrome's FileSystem to bypass the intended restrictions placed upon it. Therefore, allowing the attacker to access unauthorized files and resources within the victim's system.
The vulnerability can be demonstrated using the following code snippet
<!DOCTYPE html>
<html>
<head>
<title>CVE-2024-11117 PoC Exploit</title>
</head>
<body>
<h1>FileSystem Bypass POC (CVE-2024-11117)</h1>
<button onclick="triggerExploit()">Click to trigger exploit</button>
<script>
function triggerExploit() {
/* Bypass Chrome FileSystem restriction */
// Insert exploit logic here
}
</script>
</body>
</html>
An unsuspecting victim browsing to this page would be prompted to click the "Click to trigger exploit" button, which would execute the attacker's malicious script. This would trigger the FileSystem bypass, potentially leading to unauthorized access to the victim's data.
Please note that the specific details and exploit logic have been omitted intentionally to prevent misuse.
