CVE-2020-1350

Status: AnalyzedCritical (10)⚠ Active exploitation💥 PoC

A remote code execution vulnerability exists in Windows Domain Name System servers when they fail to properly handle requests, aka 'Windows DNS Server Remote Code Execution Vulnerability'.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Base score: 10

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 97%
Percentile among all scored CVEs: 100
Score date: 10/8/2026

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).

CISA KEV — actively exploited

Added to catalog: 11/3/2021
Remediation due date: 5/3/2022
Known ransomware use: Unknown

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
