Stack-based buffer overflow in Windows Device Association Service allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Stack-based buffer overflow in the Windows Device Association Service enables an authenticated, low-privileged network attacker to escalate privileges to full system compromise across Windows 10, Windows 11, and Windows Server 2012 through 2025. The vulnerability (CWE-121) requires user interaction to trigger but delivers complete confidentiality, integrity, and availability impact upon successful exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privilege account with network access to the target system (PR:L/AV:N) and some form of user interaction on the target host (UI:R) - likely inducing a local user to initiate or accept a device pairing or association action that exercises the vulnerable Device Association Service code path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.0 base score reflects network accessibility (AV:N) with low complexity (AC:L), making the exploit mechanically straightforward once prerequisites are satisfied, though the low-privilege authentication requirement (PR:L) and mandatory user interaction (UI:R) serve as meaningful friction points. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the latest cumulative update via Windows Update or the Microsoft Update Catalog to bring all affected systems to the fixed build numbers documented in the EUVD advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 10, Windows 11, and Windows Server 2012-2025 systems in your environment and assess which have the Device Association Service enabled or exposed to network access. …
