DescriptionNVD
Out-of-bounds read in Windows DHCP Server allows an authorized attacker to disclose information locally.
AnalysisAI
Out-of-bounds read in the Windows DHCP Server service enables a locally authenticated, low-privileged attacker to disclose contents of process memory on affected systems. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms this is a local, low-complexity attack requiring only standard user privileges - no elevated rights or user interaction needed. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the Windows DHCP Server role must be installed and running on the target system - this is a non-default role not present on standard workstations or servers unless explicitly configured; (2) the attacker must have a valid low-privileged local or domain account with the ability to interact locally with the target host (AV:L/PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) accurately reflects constrained real-world impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged domain or local account holder with interactive or remote desktop access to a Windows Server running the DHCP Server role crafts a malformed request or invokes a vulnerable code path in the DHCP service, triggering the out-of-bounds read. The leaked memory contents are returned to the attacker and could expose sensitive data such as session credentials, cryptographic material, or configuration secrets resident in the DHCP service process memory. … |
| Remediation | Vendor-released patches are confirmed available via Microsoft Security Response Center. … Detailed patch versions, workarounds, and compensating controls in full report. |
