CVE-2024-7968 is a high-severity use-after-free vulnerability found in Google Chrome prior to version 128.0.6613.84. This vulnerability allows a remote attacker, who has convinced the user to engage in specific UI interactions, to potentially exploit heap corruption via a crafted HTML page. The CVSS score for this vulnerability is 8.8, indicating a significant risk to users of the affected product.
The risk to organizations includes potential unauthorized access and data corruption, making it essential for affected users to prioritize remediation. Given the nature of the vulnerability and its exploitation context, organizations should prioritize patching immediately.
As of now, there are no public exploits confirmed, and the vulnerability is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential impact on confidentiality, integrity, and availability is rated as high.
Organizations using affected versions of Google Chrome should address this vulnerability in their priority patch cycle to mitigate the associated risks.
Vulnerability Details
The official description states that this vulnerability allows for use after free in Autofill in Google Chrome prior to version 128.0.6613.84. The vulnerability falls under the category of CWE-416, which refers to use after free errors.
With a CVSS base score of 8.8, this vulnerability presents a critical risk. The attack vector is classified as NETWORK, and it requires low attack complexity and no privileges. User interaction is required for successful exploitation.
The vulnerability was published on August 21, 2024, and has been classified with high impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2024-7968 stems from a use-after-free condition in the Autofill feature of Google Chrome. When a user engages with specific UI elements, this flaw could lead to heap corruption. Attackers may exploit this by crafting HTML pages that manipulate the browser's behavior.
The attack vector is network-based, meaning that a user needs to be tricked into visiting a malicious page. The attack complexity is low, as no special skills are required to exploit this vulnerability.
With no privileges required, and given the necessity for user interaction, the potential for exploitation remains significant. The impacts on confidentiality, integrity, and availability are assessed as high, indicating that successful exploitation could lead to severe consequences for affected users.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is considerable, especially in environments where users are likely to engage with untrusted content. Attackers may leverage this vulnerability to perform unauthorized actions or access sensitive data.
Organizations should be aware of the potential blast radius. If exploited, the impact could extend beyond individual users to broader systems, leading to widespread data breaches or service disruptions.
Given the CVSS score of 8.8 and the lack of known exploitation, organizations must still take this vulnerability seriously. The urgency for remediation is high, and organizations should address this vulnerability in their priority patch cycle.
