說明	發佈編號：TACERT-ANA-2025102901104040 (轉發國家資安資訊分享與分析中心 NISAC-200-202510-00000308) 研究人員發現Windows SMB用戶端存在NTLM反射(NTLM Reflection)漏洞(CVE-2025-33073)。取得一般使用者權限之遠端攻擊者，可透過執行惡意腳本，迫使SMB用戶端與攻擊者控制之SMB伺服器連線並進行身分鑑別，由於SMB用戶端在驗證階段存在缺陷，攻擊者可藉此繞過安全檢核以提升至系統權限，進而控制用戶端系統。該漏洞已遭駭客利用，請儘速確認並進行修補。情資分享等級: WHITE(情資內容為可公開揭露之資訊)
