Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Timely installation of Microsoft patches directly remediates the use-after-free vulnerability in Windows Connected Devices Platform Service.

prevent

Memory protection safeguards like DEP and ASLR prevent successful arbitrary code execution from use-after-free exploits.

preventdetect

Malicious code protection mechanisms block or detect the malicious content used to trigger remote exploitation of the vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

Use-after-free RCE in client Windows service with network vector and required user interaction directly maps to client-side exploitation for code execution.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

Use after free in Windows Connected Devices Platform Service allows an unauthorized attacker to execute code over a network.

Deeper analysisAI

CVE-2025-49724 is a use-after-free vulnerability (CWE-416) in the Windows Connected Devices Platform Service. Published on 2025-07-08, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and enables an unauthorized attacker to execute code over a network.

The vulnerability can be exploited remotely by an attacker with no privileges who tricks a user into performing an action, such as interacting with malicious content. Successful exploitation allows arbitrary code execution, potentially compromising confidentiality, integrity, and availability with high impact under an unchanged scope.
