CVE-2024-4671 is a critical use-after-free vulnerability in the Visuals component of Google Chrome, specifically affecting versions prior to 124.0.6367.201. This vulnerability allows a remote attacker who has compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. The severity of this vulnerability is underscored by its CVSS score of 9.6, indicating a significant risk to organizations using affected versions of the browser.
Risk to organizations includes potential unauthorized access to sensitive information, as attackers may leverage this vulnerability to gain elevated privileges or execute arbitrary code within the context of the user’s session. Given the critical nature of this vulnerability and its potential exploitability, organizations should prioritize patching immediately.
Currently, there are no public exploits available for this vulnerability, but it has been added to the Known Exploited Vulnerabilities (KEV) catalog, indicating that it is of high concern. Organizations must remain vigilant and ensure that their systems are updated to the latest version to mitigate the risks associated with this vulnerability.
As this vulnerability has high-profile implications, proactive measures should be taken to assess and enhance the security posture of all systems utilizing Google Chrome. Timely remediation is essential to prevent potential exploitation.
Vulnerability Details
The vulnerability detailed in CVE-2024-4671 is specifically classified as a use-after-free vulnerability, where memory that has been freed is accessed, leading to unpredictable behavior. The CVSS score of 9.6 reflects its critical severity, with a high impact on confidentiality, integrity, and availability. The affected products include Google Chrome and Fedora systems versions 38, 39, and 40.
This vulnerability was officially disclosed on May 14, 2024. It falls under the Common Weakness Enumeration (CWE) classification of CWE-416, which pertains to use after free errors.
Technical Analysis
The root cause of CVE-2024-4671 is a failure to properly manage memory allocation and deallocation within the Visuals component of Google Chrome. This leads to potential exploitation vectors where an attacker can craft a malicious HTML page designed to manipulate the rendering process, allowing for unauthorized actions outside the intended sandbox environment.
The attack vector is network-based, which means that exploitation could occur remotely without the need for physical access to the target system. The attack complexity is assessed as low, and the attacker does not require any privileges to exploit this vulnerability, making it particularly dangerous. User interaction is required, as the victim would need to visit the compromised HTML page.
If successfully exploited, the attacker could achieve a high impact on confidentiality, integrity, and availability, potentially leading to complete system compromise. This highlights the necessity for organizations to remain vigilant and ensure they are using updated software versions.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks to organizations. Given the widespread use of Google Chrome and its integration into many enterprise environments, the potential impact of exploitation is extensive. Attackers may leverage this vulnerability to perform actions such as data exfiltration, unauthorized access to sensitive information, or even deploying further malicious payloads.
The blast radius for this vulnerability could extend to any user of the affected versions of Google Chrome, with ramifications for both individual users and organizational security. This vulnerability's critical status in the KEV catalog further emphasizes the urgency for organizations to assess their risk based on the CVSS score and their specific usage of the affected products.
Organizations should assess their deployment of Google Chrome and ensure that they prioritize patching this vulnerability. The urgency to remediate this vulnerability is critical, as failure to do so could result in significant security incidents.
