Summary
Missing authorization in DNS Server allows an authorized attacker to perform tampering locally. The flaw stems from insufficient permission checks when accessing DNS server resources.
Risk Assessment
An authenticated user could locally modify DNS server data, potentially leading to DNS response spoofing and traffic redirection within the organization.
Recommendation
Apply available security updates for the DNS Server as soon as possible and restrict local access to the service to trusted accounts only.
