What is CVE-2024-30088?

CVE-2024-30088 is a significant vulnerability affecting the Windows operating system, specifically within the Windows Kernel. This vulnerability concerns elevation of privilege, which allows unauthorized users to gain higher access rights than intended. The implications for organizations are severe, as successful exploitation can lead to unauthorized execution of commands, compromising system integrity, and possibly leading to broader network breaches. As Windows is widely used across various sectors, the risk posed by this vulnerability can have far-reaching consequences on organizational security.

Technical Details

CVE-2024-30088 represents a flaw in the way the Windows Kernel handles specific operations, enabling a standard user or attacker to exploit this weakness to escalate their privileges. The Windows Kernel is a core component of the operating system that manages system resources and facilitates communication between hardware and software. Exploiting this vulnerability could permit attackers to execute arbitrary code with elevated privileges, potentially allowing full control of the affected system or environment. This could be achieved through various means, including malware or targeted attacks.

Impact of the Vulnerability

Unauthorized Access: The primary risk associated with CVE-2024-30088 is that it allows attackers to gain elevated privileges on a compromised system. This unauthorized access can lead to significant security breaches, as attackers may manipulate system settings, access sensitive data, or create backdoors for future access.
System Compromise: With escalated privileges, attackers could execute arbitrary code on the affected systems. This capability could enable selective targeting of critical infrastructure, application manipulation, or the installation of additional malicious software, amplifying the security risks within an organization.
Potential for Widespread Exploitation: The exploitability of this vulnerability in the wild increases the urgency for organizations to address it. As it may be leveraged by various threat actors, including sophisticated ransomware groups, organizations face heightened risks of data exfiltration, ransomware deployment, and comprehensive system disruptions.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace as recent news articles suggest the vulnerability is being used by ransomware groups.

The CISA's recommendation is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Affected Version(s)

Windows 10 Version 1507 32-bit Systems 10.0.10240.0 < 10.0.10240.20680

Windows 10 Version 1607 32-bit Systems 10.0.14393.0 < 10.0.14393.7070

Windows 10 Version 1809 32-bit Systems 10.0.17763.0 < 10.0.17763.5936

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
