CVE-2006-0988

High
Published: Translated: NVD NIST

Summary

The default configuration of the DNS Server service on Windows Server 2003, Windows 2000, and Microsoft DNS Server on Windows NT 4.0 allows recursive queries and provides additional delegation information to arbitrary IP addresses. This enables remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.

Risk Assessment

The organization is at risk of Denial of Service attacks that can overwhelm the DNS server and disrupt network operations, leading to service unavailability.

Recommendation

Disable recursive queries for untrusted IP addresses and restrict delegation information to authorized servers only.
