Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates CVE-2025-53145 by requiring timely application of vendor patches as detailed in the MSRC update guide.
Restricts or disables unnecessary functionality like Windows Message Queuing to eliminate exposure to this network-service vulnerability.
Implements memory safeguards such as DEP and ASLR that impede arbitrary code execution from type confusion exploits.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Type confusion in MSMQ service directly enables remote code execution by an authenticated low-privileged attacker over the network.
NVD Description
Access of resource using incompatible type ('type confusion') in Windows Message Queuing allows an authorized attacker to execute code over a network.
Deeper analysisAI
CVE-2025-53145 is a type confusion vulnerability (CWE-843), described as access of a resource using an incompatible type, affecting the Windows Message Queuing service. Published on 2025-08-12, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for remote exploitation.
An authorized attacker with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation allows arbitrary code execution, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) within the affected system's scope (S:U).
The Microsoft Security Response Center has published an update guide for this vulnerability, available at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-53145, which provides details on patches and mitigation recommendations.
