Description
The DNS server in Microsoft Windows 2000 Server SP4, and Server 2003 SP1 and SP2, uses predictable transaction IDs when querying other DNS servers, which allows remote attackers to spoof DNS replies, poison the DNS cache, and facilitate further attack vectors.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
