Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target system must have the Windows DHCP Server role explicitly installed and the DHCP Server service actively running - this role is not present in default Windows Server or Windows 10 installations and must be deliberately configured. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.5 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) characterizes this as a remotely exploitable, unauthenticated, low-complexity information disclosure with high confidentiality impact. … 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 Microsoft security update for CVE-2026-69930 via Windows Update, WSUS, or Microsoft Update Catalog targeting the fixed builds: Windows Server 2025 ≥ 10.0.26100.33438, Windows Server 2022 ≥ 10.0.20348.5622, Windows Server 2019 ≥ 10.0.17763.9245, Windows Server 2016 ≥ 10.0.14393.9512, Windows Server 2012 R2 ≥ 6.3.9600.23397, and Windows Server 2012 ≥ 6.2.9200.26349. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running the DHCP Server role (Windows Server 2012, 2016, 2019, 2022, 2025 and Windows 10) and categorize by criticality. …
