CVE-2025-50177: 
vulnerability analysis and mitigation

CVE-2025-50177 is a critical remote code execution vulnerability affecting Microsoft Message Queuing (MSMQ). The vulnerability was discovered and disclosed on August 12, 2025, affecting multiple versions of Windows operating systems including Windows Server 2008 through Windows Server 2025, and Windows 10 through Windows 11 versions (NVD).

The vulnerability is characterized by a use-after-free and race condition vulnerability in Windows Message Queuing, with a CVSS score of 8.1 (HIGH). The technical exploitation requires high attack complexity as attackers need to win a race condition by sending specially crafted MSMQ packets in rapid sequence over HTTP to an MSMQ server. The vulnerability is classified under CWE-416 (Use After Free) and CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization) (NVD, CrowdStrike).

When successfully exploited, this vulnerability allows unauthenticated remote attackers to execute arbitrary code over a network without user interaction. The impact is considered high for confidentiality, integrity, and availability of affected MSMQ systems, potentially leading to complete system compromise (CrowdStrike).

Microsoft has released an official fix for this vulnerability as part of the August 2025 Patch Tuesday updates. Organizations are advised to apply the security updates to all affected systems (CrowdStrike).
