CVE-2020-1228
Status: ModifiedMedium (6.5)—
<p>A denial of service vulnerability exists in Windows DNS when it fails to properly handle queries. An attacker who successfully exploited this vulnerability could cause the DNS service to become nonresponsive.</p> <p>To exploit the vulnerability, an authenticated attacker could send malicious DNS queries to a target, resulting in a denial of service.</p> <p>The update addresses the vulnerability by correcting how Windows DNS processes queries.</p>
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Base score: 6.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 4.50%
- Percentile among all scored CVEs: 91
- Score date: 10/11/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
