CVE-2025-53144 is a vulnerability classified under CWE-843 (Access of Resource Using Incompatible Type, or 'Type Confusion') affecting Microsoft Windows 10 Version 1809, specifically in the Windows Message Queuing (MSMQ) service. The vulnerability occurs due to improper handling of resource types within MSMQ, which leads to type confusion. This flaw allows an attacker who is authorized on the network with low privileges to craft malicious messages that exploit this type confusion to execute arbitrary code remotely on the target system. The attack vector is network-based (AV:N), requiring only low attack complexity (AC:L) and low privileges (PR:L), with no user interaction (UI:N) needed, making it a potent threat. The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating full system compromise potential. The vulnerability was published on August 12, 2025, with no known exploits in the wild yet. The affected version is Windows 10 Version 1809 (build 10.0.17763.0), which remains in use in many enterprise environments despite being an older release. The lack of available patches at the time of publication means organizations must rely on interim mitigations. The vulnerability's nature allows remote code execution, which could lead to lateral movement, data theft, or disruption of services within affected networks.

For European organizations, the impact of CVE-2025-53144 is significant due to the widespread use of Windows 10 Version 1809 in enterprise and industrial environments. Successful exploitation can lead to full system compromise, allowing attackers to steal sensitive data, disrupt operations, or deploy ransomware and other malware. Critical infrastructure sectors such as energy, finance, healthcare, and government agencies are particularly at risk, as they often rely on legacy Windows systems and networked services like MSMQ. The vulnerability's remote exploitability without user interaction increases the risk of rapid propagation within networks. This could lead to large-scale outages or breaches affecting multiple organizations and supply chains across Europe. Additionally, the high impact on confidentiality, integrity, and availability means that exploited systems could be used as footholds for further attacks, threatening national security and economic stability.

1. Apply official patches from Microsoft immediately once they become available for Windows 10 Version 1809 to remediate the vulnerability. 2. Until patches are released, restrict network access to the Windows Message Queuing service by implementing strict firewall rules and network segmentation to limit exposure to trusted hosts only. 3. Disable MSMQ on systems where it is not required to reduce the attack surface. 4. Monitor network traffic for unusual MSMQ activity or anomalous message patterns that could indicate exploitation attempts. 5. Employ endpoint detection and response (EDR) solutions to detect and respond to suspicious process behaviors indicative of code execution exploits. 6. Review and enforce the principle of least privilege for users and services interacting with MSMQ to minimize the potential impact of compromised accounts. 7. Conduct regular vulnerability scanning and penetration testing focusing on legacy systems to identify and remediate similar risks proactively. 8. Maintain up-to-date asset inventories to identify all systems running Windows 10 Version 1809 and prioritize their remediation.
