Vulnerability AssessmentAI
| Exploitation | Physical access to the target machine is mandatory - the AV:P vector rules out any remote or network-based exploitation path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N yields a base score of 4.6, which accurately reflects the physical access prerequisite that fundamentally constrains real-world risk. … 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 | The primary fix is to apply the Microsoft Security Update released via Windows Update or WSUS, targeting the build thresholds specified per version: Windows 10 1809/Server 2019 to 10.0.17763.9245 or later; Windows 10 21H2 to 10.0.19044.7725 or later; Windows 10 22H2 to 10.0.19045.7725 or later; Windows 11 23H2 to 10.0.22631.7582 or later; Windows 11 24H2/Server 2025 to 10.0.26100.9445 (client) or 10.0.26100.33438 (server) or later; Windows 11 25H2 to 10.0.26200.9445 or later; Windows 11 26H1 to 10.0.28000.2954 or later; Windows Server 2022 to 10.0.20348.5622 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
