CVE-2023-3214: Use after free in Google Chrome
Use after free in Autofill payments in Google Chrome prior to 114.0.5735.133 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)
AI Analysis
Technical Summary
CVE-2023-3214 is a critical use-after-free vulnerability identified in the Autofill payments component of Google Chrome versions prior to 114.0.5735.133. This vulnerability arises when the browser incorrectly manages memory related to the Autofill payments feature, leading to a use-after-free condition. Specifically, a remote attacker can craft a malicious HTML page that triggers heap corruption by exploiting this memory mismanagement. The vulnerability is exploitable remotely without requiring any privileges, but it does require user interaction, such as visiting a malicious webpage. The CVSS v3.1 score of 8.8 reflects the high severity of this flaw, indicating that successful exploitation could lead to complete compromise of confidentiality, integrity, and availability of the affected system. The vulnerability falls under CWE-416 (Use After Free), a common and dangerous class of memory corruption bugs that can lead to arbitrary code execution. Although no known exploits are currently reported in the wild, the critical nature of the vulnerability and its presence in a widely used browser make it a significant security concern. The vulnerability was publicly disclosed on June 13, 2023, and users are advised to update to Chrome version 114.0.5735.133 or later where the issue has been addressed.
Potential Impact
For European organizations, the impact of CVE-2023-3214 can be substantial. Google Chrome is one of the most widely used browsers in Europe across both enterprise and consumer environments. Exploitation of this vulnerability could allow attackers to execute arbitrary code remotely, potentially leading to data breaches, unauthorized access to sensitive information, and disruption of business operations. Given the vulnerability affects the Autofill payments feature, attackers might also target financial data or payment credentials stored or processed by the browser, increasing the risk of financial fraud and identity theft. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitivity of the data handled and the potential for cascading effects from a successful compromise. Furthermore, the requirement for user interaction (visiting a malicious site) means phishing campaigns or malicious advertisements could be vectors for exploitation, which are common attack methods in Europe. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the critical severity demands immediate attention to prevent potential future attacks.
Mitigation Recommendations
To mitigate the risks posed by CVE-2023-3214, European organizations should implement the following specific measures: 1) Immediate deployment of Google Chrome updates to version 114.0.5735.133 or later across all enterprise-managed devices and encourage users to update personal devices. 2) Implement strict web filtering and URL reputation services to block access to known malicious websites and reduce the risk of users encountering crafted HTML pages designed to exploit this vulnerability. 3) Enhance user awareness training focusing on phishing and social engineering tactics that could lead to user interaction with malicious content. 4) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behaviors indicative of exploitation attempts, such as unusual memory corruption or code execution patterns. 5) Restrict or monitor the use of browser Autofill features for payments in sensitive environments, potentially disabling Autofill for payment data where feasible to reduce attack surface. 6) Regularly audit and monitor browser extensions and plugins, as these can sometimes be leveraged to facilitate exploitation. 7) Maintain robust backup and incident response plans to quickly recover from potential compromises. These targeted actions go beyond generic patching advice and address the specific exploitation vectors and organizational risks associated with this vulnerability.
