CVE-2025-47984: CWE-693: Protection Mechanism Failure in Microsoft Windows 10 Version 1809
Protection mechanism failure in Windows GDI allows an unauthorized attacker to disclose information over a network.
AI Analysis
Technical Summary
CVE-2025-47984 is a high-severity vulnerability affecting Microsoft Windows 10 Version 1809 (build 10.0.17763.0). It involves a protection mechanism failure within the Windows Graphics Device Interface (GDI), a core component responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. The vulnerability is classified under CWE-693, which pertains to protection mechanism failures, indicating that security controls intended to prevent unauthorized access or information disclosure are improperly implemented or bypassed. Specifically, this flaw allows an unauthorized attacker to remotely disclose sensitive information over a network without requiring any authentication or user interaction. The CVSS 3.1 base score of 7.5 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (C:H), with no impact on integrity or availability. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component and does not propagate to other components. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. The absence of published patches at this time increases the urgency for affected organizations to monitor for updates and implement interim mitigations. The vulnerability's exploitation could allow attackers to extract sensitive graphical data or memory contents related to GDI operations, potentially exposing confidential information such as graphical assets, user interface elements, or other data processed by GDI. Given that Windows 10 Version 1809 is an older release, some organizations may still be running it in legacy environments, increasing their exposure.
Potential Impact
For European organizations, the impact of CVE-2025-47984 is primarily the unauthorized disclosure of sensitive information over the network, which could lead to data breaches involving confidential graphical or memory data processed by Windows GDI. This could affect sectors handling sensitive or regulated data, such as finance, healthcare, government, and critical infrastructure. The vulnerability's network-based exploitation vector means attackers can potentially target exposed systems remotely without needing credentials or user interaction, increasing the risk of widespread reconnaissance or data leakage. Organizations relying on Windows 10 Version 1809 in production or legacy systems may face compliance risks under GDPR if personal or sensitive data is exposed. Additionally, the information disclosed could be leveraged in subsequent attacks, such as privilege escalation or lateral movement, compounding the threat. The lack of known exploits currently may provide a window for proactive defense, but the high severity score and ease of exploitation necessitate urgent attention to prevent potential future attacks.
Mitigation Recommendations
1. Immediate Upgrade: Organizations should prioritize upgrading systems from Windows 10 Version 1809 to a supported and patched version of Windows 10 or Windows 11, as Microsoft typically provides security fixes in newer releases. 2. Network Segmentation: Isolate legacy systems running Windows 10 Version 1809 from critical network segments and limit their exposure to untrusted networks to reduce the attack surface. 3. Monitor Network Traffic: Deploy network intrusion detection systems (NIDS) and monitor for unusual or unauthorized network activity targeting GDI-related services or ports. 4. Apply Principle of Least Privilege: Restrict network access and user permissions on affected systems to minimize potential exploitation pathways. 5. Disable Unnecessary Services: Identify and disable any unnecessary graphical or remote display services that rely on GDI components if feasible. 6. Incident Response Preparation: Develop and test incident response plans specific to information disclosure events, including forensic analysis of GDI-related memory or graphical data leaks. 7. Stay Informed: Continuously monitor Microsoft security advisories for patches or workarounds related to CVE-2025-47984 and apply them promptly upon release. 8. Use Endpoint Protection: Employ advanced endpoint detection and response (EDR) tools capable of detecting anomalous behavior related to GDI exploitation attempts.
