Windows DHCP Server Elevation of Privilege Vulnerability

Noroxi assessment

Priority: Monitor (action score 27/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.72% (FIRST EPSS); higher than 52.7% of all records.
Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: Windows 10 Version 1607 for 32-bit Systems 10.0.14393.9512; Windows 10 Version 1607 for x64-based Systems 10.0.14393.9512; Windows 10 Version 1809 for 32-bit Systems 10.0.17763.9245.

Low priority for now. Upgrade to Windows 10 Version 1607 for 32-bit Systems 10.0.14393.9512; Windows 10 Version 1607 for x64-based Systems 10.0.14393.9512; Windows 10 Version 1809 for 32-bit Systems 10.0.17763.9245 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Missing authentication for critical function in Windows DHCP Server allows an authorized attacker to elevate privileges over a network.
