Heap-based buffer overflow in Windows DHCP Server allows an authorized attacker to execute code locally.
AnalysisAI
Heap-based buffer overflow (CWE-122) in the Windows DHCP Server service enables an authorized local attacker with administrative privileges to execute arbitrary code on affected Windows Server systems. The vulnerability spans Windows Server 2012 through 2025 as well as Windows 10 versions 1607 and 1809, and requires that the DHCP Server role be installed and running. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the Windows DHCP Server role must be installed and active on the target system - this is an opt-in server role, not present by default on all Windows Server installations; (2) the attacker must have local access to the system with high-privilege credentials (PR:H), consistent with the 'authorized attacker' framing in the description; (3) heap manipulation to achieve reliable code execution adds AC:H complexity, meaning a working exploit likely requires specific OS version and heap state conditions rather than a trivial one-shot trigger. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.4 (Medium) accurately reflects meaningful exploitation constraints: AV:L (attacker must have local system access), AC:H (heap exploitation requires precise memory layout manipulation), and PR:H (high privileges needed - described as an 'authorized attacker'). … 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 | Vendor-released patches are available for all affected versions via Windows Update and Microsoft Update Catalog. … Detailed patch versions, workarounds, and compensating controls in full report. |
