CVE-2024-0519 is a vulnerability identified in the V8 JavaScript engine component of Google Chrome versions prior to 120.0.6099.224. The issue stems from an out-of-bounds memory access, classified under CWE-125 (Out-of-bounds Read) and CWE-787 (Out-of-bounds Write), which can lead to heap corruption. When a user navigates to a specially crafted HTML page, the malicious code can trigger this memory corruption, potentially allowing an attacker to execute arbitrary code within the context of the browser process. This can compromise the confidentiality, integrity, and availability of the user's system. The vulnerability is remotely exploitable over the network without requiring prior authentication, but it does require user interaction in the form of visiting a malicious web page. The CVSS v3.1 base score is 8.8, reflecting high severity due to the ease of exploitation (low attack complexity), no privileges required, and the potential for complete system compromise. While no public exploits have been reported yet, the nature of the vulnerability and its presence in a widely used browser make it a critical risk. The lack of patch links in the provided data suggests users should update to Chrome version 120.0.6099.224 or later, where the issue is resolved. Organizations should prioritize this update to prevent exploitation.

For European organizations, this vulnerability poses a significant risk due to the widespread use of Google Chrome as a primary web browser. Successful exploitation can lead to arbitrary code execution, allowing attackers to steal sensitive data, install malware, or disrupt operations. Sectors with high web exposure such as finance, government, healthcare, and critical infrastructure are particularly vulnerable. The compromise of endpoints through this vulnerability could facilitate lateral movement within networks, data breaches, or ransomware deployment. Given the ease of exploitation and the potential for severe impact on confidentiality, integrity, and availability, organizations face risks including data loss, operational downtime, reputational damage, and regulatory penalties under GDPR if personal data is compromised. The requirement for user interaction means phishing or malicious websites could be vectors, emphasizing the need for user awareness and technical controls.

European organizations should immediately ensure all Google Chrome installations are updated to version 120.0.6099.224 or later, where the vulnerability is patched. Deploy centralized patch management tools to enforce browser updates across all endpoints. Implement web filtering solutions to block access to known malicious sites and employ URL reputation services to reduce the risk of users visiting crafted pages. Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. Educate users on the risks of clicking unknown links or visiting untrusted websites. Consider deploying browser isolation technologies for high-risk users or environments to contain potential exploits. Regularly audit browser versions and configurations to ensure compliance with security policies. Additionally, maintain up-to-date backups and incident response plans to mitigate potential damage from successful exploitation.
