Insufficient Data Validation in Google Chrome Affects Mojo Component

CVE-2024-9369

What is CVE-2024-9369?

CVE-2024-9369 refers to a critical vulnerability found in Google Chrome, specifically impacting the Mojo component. Chrome is a widely used web browser aimed at providing a fast and secure browsing experience. This vulnerability stems from insufficient data validation, which enables a remote attacker, under certain conditions, to execute an out-of-bounds memory write via a specially crafted HTML page. Such exploitation could allow cybercriminals to manipulate system memory and potentially take control over the affected application, posing a serious threat to organizations that rely on Chrome for secure web access and transactions.

Technical Details

The vulnerability affects Google Chrome versions prior to 129.0.6668.89 and is classified under the Chromium security severity level as High. The flaw is rooted in the Mojo component, which plays a critical role in the browser’s architecture, facilitating communication between various parts of the browser's processes. By leveraging this weakness, an attacker could compromise the renderer process—where web content is processed—and manipulate it in ways that could harm the underlying system.

Potential impact of CVE-2024-9369

1. Remote Code Execution: This vulnerability could allow attackers to execute arbitrary code on the victim's system, enabling them to gain unauthorized access and control, potentially leading to data theft or further exploitation.

2. Increased Risk of Malware Infections: Should an exploit become widely available, users of affected Chrome versions could fall victim to malware, which could be injected through malicious web pages. This could lead to widespread compromises not only of individual systems but also of larger organizational networks.

3. Reputation and Financial Damage: Organizations reliant on Chrome for their operations may experience significant reputational harm and financial loss due to data breaches or the fallout from malware infections leveraged through this vulnerability. The costs associated with remediation and potential legal ramifications can also be substantial.
