CVE-2024-38107 is a high-severity privilege escalation vulnerability in Microsoft Windows, specifically related to the Windows Power Dependency Coordinator. This vulnerability allows local attackers to exploit the system and potentially gain elevated privileges, which can lead to unauthorized access and control over sensitive system resources. The CVSS score for this vulnerability is 7.8, indicating a serious risk level that organizations must address promptly.
The urgency for defenders is critical, as this vulnerability has been assigned a KEV status, meaning it is recognized as actively exploited in the wild. Organizations should prioritize patching immediately to mitigate the associated risks, which include potential unauthorized access and compromise of sensitive data.
The vulnerability affects multiple versions of Windows 10 and 11, as well as various Windows Server editions. As such, the blast radius could be significant, impacting numerous users and services across different environments. Without timely remediation, attackers could leverage this vulnerability to escalate their privileges and execute malicious activities.
Organizations are encouraged to assess their environments for exposure to this vulnerability and implement necessary updates as outlined by Microsoft. Failure to act could result in severe consequences, including data breaches and operational disruptions.
Vulnerability Details
The official description of CVE-2024-38107 states that it is a Windows Power Dependency Coordinator Elevation of Privilege Vulnerability. This vulnerability is classified under CWE-416, indicating a potential issue with a use-after-free condition.
The vulnerability is characterized by a CVSS score of 7.8, indicating high severity. The attack vector is local, requiring low complexity, and only low privileges are required to exploit the vulnerability. Importantly, user interaction is not needed for the exploit to occur. The impacts of this vulnerability are severe, with high potential consequences for confidentiality, integrity, and availability.
Microsoft has published this vulnerability as part of their security updates, emphasizing the critical nature of the flaw. It is essential for organizations using affected versions of Windows to implement the necessary updates as soon as possible.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of resources within the Windows Power Dependency Coordinator. Attackers may exploit this flaw through local access, which makes it imperative that organizations restrict physical and remote local access to their systems.
The attack complexity is classified as low, indicating that the exploitation of this vulnerability does not require advanced skills or tools, making it accessible to a broader range of potential attackers. Since only low privileges are required, even users with limited access could potentially exploit this vulnerability if they could gain local access.
Furthermore, the confidentiality, integrity, and availability impacts are all rated as high, underscoring the potential severity of the consequences if an attacker successfully exploits this vulnerability. Organizations must therefore monitor for any signs of exploitation and take preventive measures.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive systems and data, which could lead to data breaches, operational disruptions, and reputational damage. The potential blast radius is significant, given the wide range of affected Windows products, including multiple versions of Windows 10 and 11, as well as various server versions.
The urgency for organizations to address this vulnerability is high, particularly given its inclusion in the KEV catalog. The risk of exploitation is pressing, and organizations should ensure that they have robust patch management processes in place to mitigate these types of vulnerabilities promptly.
Organizations that fail to address this vulnerability risk potential exploitation, which could result in severe financial and reputational damage.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The affected versions include Windows 10 (1507, 1607, 1809, 21H2, 22H2) and Windows 11 (21H2, 22H2, 23H2, 24H2), along with Windows Server versions (2012, 2016, 2019, 2022, 2022 23H2). If specific version information is unavailable, it should be noted that all versions prior to vendor patch are affected.
Mitigation & Remediation
Organizations should prioritize applying patches as soon as they are released by Microsoft. For those unable to immediately apply patches, recommended workarounds include restricting local access and implementing network controls to limit exposure. Configuration hardening is also advised to mitigate risks associated with this vulnerability.
For ongoing protection, organizations should consider conducting regular security assessments and penetration testing to identify potential vulnerabilities in their systems. This proactive approach can help organizations maintain a robust security posture.
Continuous penetration testing can also help in identifying and mitigating similar vulnerabilities.
Detection Guidance
Organizations should monitor logs for unusual access patterns or attempts to exploit local privileges. Behavioral anomalies, such as unexpected changes in user permissions or escalated access rights, should also be flagged for review.
Network signatures indicating attempts to access unauthorized resources or execute privileged commands can serve as additional indicators of potential exploitation. Regular audits of system changes and user access rights can help detect unauthorized modifications.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2024-38107 indicates a pattern of privilege escalation vulnerabilities that continue to emerge in widely used operating systems. Security teams must learn from this incident and remain vigilant against similar threats.
This vulnerability highlights the importance of maintaining a strong patch management strategy. Organizations should regularly review and update their systems to ensure they are protected against known vulnerabilities.
Penetration testing methodology should be integrated into the overall security strategy to identify and remediate vulnerabilities proactively.
