CVE-2024-7971 is a critical type confusion vulnerability affecting Google Chrome and Microsoft Edge, with a CVSS score of 9.6. This vulnerability allows remote attackers to exploit heap corruption through crafted HTML pages, posing serious risks to users. The exploitation potential is significant, as it involves a network attack vector that requires user interaction, resulting in high impacts on confidentiality, integrity, and availability.
Given the high-profile nature of this vulnerability, organizations utilizing these browsers should prioritize immediate patching to mitigate potential exploitation. The vulnerability was publicly disclosed on August 21, 2024, and it is vital for users to update to the latest versions as soon as possible to protect against potential attacks.
As of now, known exploits are available, and the vulnerability is also included in the Known Exploited Vulnerabilities (KEV) catalog, reflecting its critical status in the threat landscape. This underscores the urgency for organizations to take proactive measures to safeguard their systems.
Organizations should prioritize patching immediately to prevent unauthorized access and potential data breaches stemming from this vulnerability.
Vulnerability Details
The vulnerability arises from type confusion in V8, the JavaScript engine used by Google Chrome. It allows attackers to exploit heap corruption when users visit a specially crafted HTML page. The CVSS vector indicates a network attack that requires low attack complexity and no privileges, but does require user interaction, making it a serious concern for users.
Affected versions include Google Chrome prior to 128.0.6613.84 and Microsoft Edge prior to 128.0.2739.42. The vulnerability has been classified under CWE-843, which relates to type confusion.
Technical Analysis
The root cause of CVE-2024-7971 lies in the handling of types within the V8 engine. This vulnerability can be exploited via a crafted HTML page, leading to heap corruption and allowing malicious actors to manipulate memory. The attack vector is network-based, meaning an attacker can exploit this vulnerability without physical access to the system, significantly heightening the risk.
The attack complexity is low, indicating that even relatively unskilled attackers could exploit this vulnerability with the right crafted payload. Attackers do not require any privileges to launch the attack, but they do require user interaction, as victims must visit the malicious HTML page. The impact of exploitation includes high confidentiality, integrity, and availability impact, making this vulnerability particularly dangerous.
Risk & Impact Analysis
The real-world risk posed by CVE-2024-7971 is significant. Organizations using affected versions of Google Chrome and Microsoft Edge are at risk of unauthorized access and data breaches. The potential blast radius is extensive, affecting users across various sectors, particularly those who rely heavily on web applications.
Given its inclusion in the KEV catalog, organizations must assess their exposure to this vulnerability and prioritize mitigation efforts. The urgency for remediation is critical due to the high CVSS score and the active exploitation in the wild.
