CVE-2024-38069: CWE-347: Improper Verification of Cryptographic Signature in Microsoft Windows 10 Version 1809
Windows Enroll Engine Security Feature Bypass Vulnerability
AI Analysis
Technical Summary
CVE-2024-38069 is a vulnerability classified under CWE-347, indicating improper verification of cryptographic signatures within the Windows Enroll Engine component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The flaw allows a security feature bypass, meaning that the system may accept cryptographic signatures that are invalid or improperly validated, undermining the trust model of the Windows enrollment process. This can lead to unauthorized actions such as installing malicious certificates or bypassing security controls that rely on signature validation. The vulnerability requires an attacker to have local access with low privileges and involves high attack complexity, meaning it is not trivially exploitable remotely or by unprivileged users without some conditions. No user interaction is required, and the scope is unchanged, but the impact on confidentiality, integrity, and availability is high, as attackers could potentially execute unauthorized code or escalate privileges. Although no exploits are currently known in the wild, the vulnerability's presence in an older Windows 10 version still widely used in enterprise environments poses a significant risk. The lack of an available patch at the time of publication necessitates immediate attention to mitigation strategies to prevent exploitation.
Potential Impact
For European organizations, this vulnerability poses a significant risk especially to those still operating legacy Windows 10 Version 1809 systems. The improper signature verification can allow attackers with local access to bypass security features, potentially leading to unauthorized code execution, privilege escalation, or installation of malicious certificates. This can compromise sensitive data confidentiality, system integrity, and availability of critical services. Sectors such as government, finance, healthcare, and critical infrastructure that rely on legacy Windows 10 deployments are particularly vulnerable. The high impact on core security mechanisms may facilitate lateral movement within networks or persistent footholds by attackers. Given the high attack complexity and requirement for local access, the threat is more relevant to insider threats or attackers who have already gained some access, but the consequences remain severe. The absence of known exploits reduces immediate risk but does not eliminate the need for urgent mitigation.
Mitigation Recommendations
1. Prioritize upgrading affected systems from Windows 10 Version 1809 to a supported, patched version of Windows 10 or later to eliminate the vulnerability. 2. Until upgrades are possible, restrict local access to vulnerable systems by enforcing strict physical and network access controls, including the use of endpoint protection and monitoring for suspicious local activity. 3. Implement application whitelisting and restrict installation of unauthorized certificates or software to reduce the risk of exploitation. 4. Monitor system logs and Windows Enroll Engine activities for anomalies that could indicate attempts to exploit signature verification weaknesses. 5. Educate IT staff about the vulnerability and ensure rapid deployment of any forthcoming patches from Microsoft. 6. Employ network segmentation to limit the impact of potential compromises on critical assets. 7. Use multi-factor authentication and least privilege principles to reduce the likelihood of attackers gaining local access with sufficient privileges.
