Overview

Recently, NSFOCUS CERT detected that Samba released a security update to fix the Samba WINS command injection vulnerability (CVE-2025-10230); Since WINS when Samba is used as an AD domain controller does not strictly verify the wins hook script command when processing registration messages, unauthenticated attackers can construct a special host name to inject commands into the target server, thereby realizing remote command execution with the Samba process. The CVSS score is 10.0. Relevant users are requested to take measures for protection as soon as possible.
