CVE-2025-50177 is a high-severity Race Condition (CWE-362) vulnerability in Microsoft Windows Server 2008. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 41.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 CM-7 (Least Functionality) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-2 Flaw Remediation requires timely patching of the specific use-after-free vulnerability in Windows Message Queuing to eliminate remote code execution risk.
SI-16 Memory Protection deploys runtime mitigations such as ASLR and DEP to directly counter exploitation of use-after-free memory corruption in Windows Message Queuing.
CM-7 Least Functionality prohibits or restricts unnecessary network-exposed services like Windows Message Queuing to prevent unauthorized remote access and exploitation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Use-after-free in network-accessible Windows Message Queuing service directly enables remote unauthenticated arbitrary code execution (T1190: Exploit Public-Facing Application).
NVD Description
Use after free in Windows Message Queuing allows an unauthorized attacker to execute code over a network.
Deeper analysisAI
CVE-2025-50177 is a use-after-free vulnerability (CWE-416) in Windows Message Queuing, also associated with CWE-362 (concurrent execution using shared resource with improper synchronization). Published on 2025-08-12, it carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity with network accessibility, high attack complexity, no required privileges or user interaction, unchanged scope, and high impacts on confidentiality, integrity, and availability.
An unauthorized attacker with network access can exploit this vulnerability remotely. The high attack complexity suggests sophisticated techniques are needed, but successful exploitation allows arbitrary code execution on the target system without privileges or user involvement.
