## How to fix

- Fixed in Build 6301

## Technical details

The vulnerability is a PowerShell injection in the TXT record value processing logic for Windows DNS operations. Affected versions fail to properly validate user-supplied TXT record values before incorporating them into PowerShell commands executed on managed Windows DNS servers. An authenticated attacker with DNS zone management privileges can inject malicious PowerShell commands through specially crafted TXT record values, achieving remote code execution on the Windows server with the privileges of the DDI Central service account.
