CVE-2024-6768 is classified as a Denial of Service vulnerability affecting CLFS.sys in Microsoft Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, and Windows Server 2022. This vulnerability allows a malicious authenticated low-privilege user to cause a Blue Screen of Death (BSOD) via a forced call to the KeBugCheckEx function. The severity is rated as medium with a CVSS score of 6.8, indicating the need for attention from organizations.Risk to organizations includes potential downtime and disruption of services resulting from system crashes. The low privileges required to exploit this vulnerability make it a concerning issue, particularly in environments where authenticated users have access to critical systems.As of the publication date, this vulnerability is classified as 'Awaiting Analysis', indicating that a detailed assessment of its impact and exploitability is ongoing. However, organizations should prioritize remediation due to the potential for exploitation by low-privilege users.Organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with potential exploitation.
Vulnerability Details
The official description for CVE-2024-6768 states that it allows a malicious authenticated low-privilege user to cause a Blue Screen of Death in Microsoft Windows environments. The vulnerability is categorized under CWE-1284, indicating an issue related to improper resource management.With a CVSS score of 6.8, the vulnerability is categorized as medium severity. The attack vector is local, requiring low privileges and no user interaction, which increases its potential for exploitation in certain environments.The vulnerability was published on August 12, 2024, and is currently awaiting further analysis. Organizations should remain vigilant for updates regarding this vulnerability's status and potential patches.
Technical Analysis
The root cause of CVE-2024-6768 lies in the CLFS.sys driver, which, when called with specific parameters, can trigger a system crash. The attack vector is local, meaning an attacker must have access to the system to exploit the vulnerability. The attack complexity is low, as it does not require significant technical skill to execute.Since the vulnerability only requires low privileges, it poses a significant risk to organizations that may have multiple low-privilege accounts. No user interaction is needed, making automated exploitation a possibility. The availability impact is rated as high, as the system becomes unusable following a successful exploit.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-6768 is significant, particularly in environments where low-privilege users have access to sensitive systems. The potential for a Blue Screen of Death can lead to service disruptions that affect business operations.Given the current CVSS score of 6.8, organizations should assess their exposure and prioritize this vulnerability in their patch management processes. The risk of exploitation is non-negligible, especially in environments with multiple authenticated users.Organizations are advised to schedule remediation efforts to address this vulnerability and minimize the risk of incidents that can arise from system instability.
