CVE-2023-2724: Type Confusion in Google Chrome
Type confusion in V8 in Google Chrome prior to 113.0.5672.126 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
CVE-2023-2724 is a high-severity type confusion vulnerability found in the V8 JavaScript engine used by Google Chrome versions prior to 113.0.5672.126. Type confusion occurs when a program incorrectly interprets a piece of memory as a different data type than it actually is, which can lead to memory corruption issues. In this case, the vulnerability allows a remote attacker to exploit heap corruption by crafting a malicious HTML page that triggers the flaw in V8. This heap corruption can potentially be leveraged to execute arbitrary code within the context of the browser, compromising confidentiality, integrity, and availability of the affected system. The vulnerability requires no privileges (PR:N) but does require user interaction (UI:R), meaning the victim must visit or interact with a malicious web page. The CVSS 3.1 base score is 8.8, indicating a high severity with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the nature of the vulnerability and its presence in a widely used browser make it a critical concern. The vulnerability is categorized under CWE-843 (Type Confusion), which is a common source of memory corruption bugs in C++ applications like V8. Since Chrome is a dominant browser globally, this vulnerability poses a significant risk to users who have not updated to the patched version 113.0.5672.126 or later. The absence of patch links in the provided data suggests organizations should verify updates directly from official Google Chrome channels to remediate this issue promptly.
Potential Impact
For European organizations, the impact of CVE-2023-2724 can be substantial due to the widespread use of Google Chrome as a primary web browser in corporate and public sectors. Successful exploitation could allow attackers to execute arbitrary code remotely, potentially leading to data breaches, unauthorized access to sensitive information, and disruption of business operations. This is particularly critical for sectors handling sensitive personal data under GDPR, such as finance, healthcare, and government agencies. The vulnerability could be exploited to bypass browser sandboxing mechanisms, enabling attackers to escalate privileges or move laterally within networks. Additionally, since the attack requires user interaction, phishing campaigns or malicious advertisements could be used as vectors, increasing the risk of targeted attacks against European entities. The high confidentiality, integrity, and availability impacts mean that exploitation could result in data theft, manipulation, or denial of service, all of which have regulatory and reputational consequences for affected organizations.
Mitigation Recommendations
European organizations should immediately ensure all Google Chrome installations are updated to version 113.0.5672.126 or later, as this is the primary and most effective mitigation. IT departments should enforce automated browser updates or deploy managed update policies to prevent delays in patching. Additionally, organizations should implement web filtering solutions to block access to known malicious websites and employ advanced threat protection tools capable of detecting and mitigating exploit attempts targeting browser vulnerabilities. User awareness training should emphasize the risks of interacting with untrusted web content and phishing links, reducing the likelihood of successful exploitation. Network segmentation and endpoint detection and response (EDR) solutions can help detect suspicious behaviors resulting from exploitation attempts. Finally, monitoring browser crash logs and unusual process behaviors can provide early indicators of exploitation attempts related to heap corruption vulnerabilities.
