CVE-2007-3898

Status: ModifiedMedium (6.4)—💥 Exploit

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.

CVSS

Exploitation probability (EPSS)

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).

💥 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.
