CVE-2024-38180: CWE-693: Protection Mechanism Failure in Microsoft Windows 10 Version 1809
Windows SmartScreen Security Feature Bypass Vulnerability
AI Analysis
Technical Summary
CVE-2024-38180 is a high-severity vulnerability affecting Microsoft Windows 10 Version 1809, specifically targeting the Windows SmartScreen security feature. SmartScreen is designed to protect users by warning or blocking the execution of unrecognized or potentially malicious applications and files. The vulnerability is classified under CWE-693, which relates to protection mechanism failures, indicating that the security controls intended to prevent malicious activity can be bypassed. The CVSS 3.1 base score of 8.8 reflects a critical impact on confidentiality, integrity, and availability, with an attack vector that is network-based, requires no privileges, but does require user interaction. The vulnerability allows an attacker to bypass SmartScreen protections, potentially enabling the execution of malicious code that would otherwise be blocked or flagged. This bypass could lead to unauthorized code execution, data compromise, or system disruption. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk, especially for systems that remain unpatched. The affected version, Windows 10 1809 (build 10.0.17763.0), is an older release but still in use in various environments, particularly in enterprise settings where legacy systems persist. The lack of available patches at the time of publication increases the urgency for mitigation and risk management.
Potential Impact
For European organizations, the impact of this vulnerability is substantial. Many enterprises and public sector entities in Europe continue to operate legacy Windows 10 1809 systems due to compatibility requirements or delayed upgrade cycles. A successful SmartScreen bypass could facilitate the delivery and execution of malware, ransomware, or advanced persistent threats, leading to data breaches, operational disruptions, and financial losses. The compromise of confidentiality could expose sensitive personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Integrity violations could undermine trust in critical business applications, while availability impacts could disrupt essential services. Given the network attack vector and no privilege requirement, attackers could target users through phishing or malicious websites, increasing the risk of widespread infection. The requirement for user interaction means social engineering remains a key attack vector, which is a common challenge in European organizations with diverse user bases. The absence of known exploits in the wild currently provides a window for proactive defense, but the high CVSS score indicates that exploitation would be highly damaging if it occurs.
Mitigation Recommendations
European organizations should prioritize the following specific mitigation steps: 1) Identify and inventory all systems running Windows 10 Version 1809 to assess exposure. 2) Where possible, upgrade affected systems to a supported and patched Windows version to eliminate the vulnerability. 3) Until upgrades are feasible, implement application whitelisting and restrict execution of untrusted or unknown applications to reduce reliance on SmartScreen. 4) Enhance email and web filtering to block phishing attempts and malicious URLs that could trigger the vulnerability. 5) Conduct targeted user awareness training focusing on the risks of interacting with untrusted content and recognizing social engineering tactics. 6) Employ endpoint detection and response (EDR) solutions to monitor for suspicious behaviors indicative of exploitation attempts. 7) Monitor security advisories from Microsoft for the release of patches or workarounds and apply them promptly. 8) Consider network segmentation to limit the spread of potential malware originating from exploited endpoints. These measures go beyond generic advice by focusing on compensating controls and proactive detection tailored to the specific vulnerability and affected environment.
