Missing authorization in Windows Modern Device Management (MDM) allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in Windows Modern Device Management (MDM) allows a locally authenticated, low-privileged attacker to gain full system-level control without additional user interaction. The root cause is CWE-862 (Missing Authorization): the MDM component fails to enforce authorization checks on operations that should require elevated privileges, enabling an attacker who already has local access to escalate to SYSTEM or equivalent. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to hold a locally authenticated low-privileged Windows session on the target machine (PR:L, AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 (High) score is consistent with the provided vector: local access is required (AV:L) with low privileges (PR:L), making this a post-authentication local privilege escalation rather than a remote threat. … 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 vendor-released security update via Windows Update or WSUS targeting the fixed build for each affected OS: Windows 10 1809 → 10.0.17763.9245, Windows 10 21H2 → 10.0.19044.7725, Windows 10 22H2 → 10.0.19045.7725, Windows 11 23H2 → 10.0.22631.7582, Windows 11 24H2 → 10.0.26100.9445, Windows 11 25H2 → 10.0.26200.9445, Windows 11 26H1 → 10.0.28000.2954, Windows Server 2019 → 10.0.17763.9245, Windows Server 2022 → 10.0.20348.5622, Windows Server 2025 → 10.0.26100.33438. … Detailed patch versions, workarounds, and compensating controls in full report. |
