Cause

詳情:  

  • 緩衝區溢位漏洞 (CVE-2019-3705)
     
Dell Technologies 2.92 之前的 iDRAC6 版本、2.61.60.60 之前的 iDRAC7/iDRAC8 版本,以及 3.20.21.20、3.21.24.22、3.21.26.22 和 3.23.23.23 之前的 iDRAC9 版本,包含堆疊式緩衝區溢位漏洞。未經身份驗證的遠端攻擊者可能會利用此漏洞,通過向受影響的系統發送特別構建的輸入數據,使 Web 伺服器崩潰或以 Web 伺服器許可權在系統上執行任意代碼。

CVSSv3 基本分數 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
 
  • Web 介面驗證繞過漏洞 (CVE-2019-3706)
 
3.24.24.24、3.21.26.22、3.22.22.22 及 3.21.25.22 之前的 Dell Technologies iDRAC9 版本包含一個認證略過漏洞。遠端攻擊者可能會利用此漏洞略過驗證,並透過將特別設計的資料傳送至 iDRAC Web 介面,以取得系統存取權。

CVSSv3 基本分數 8.6 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H)
 
  • WS-MAN 驗證略過漏洞 (CVE-2019-3707)
 
在 3.30.30.30 之前的 Dell Technologies iDRAC9 版本包含一個驗證略過漏洞。遠端攻擊者可能會利用此漏洞繞過身份驗證,並通過向 WS-MAN 介面發送特製輸入數據來獲取對系統的訪問許可權。
 
CVSSv3 基本分數 8.6 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H)

Dell 關於 iDRAC 的最佳實務

除了維護最新的 iDRAC 韌體,Dell 也會提供下列建議:

  • iDRAC 並非設計或打算放置在網際網路上或連線至網際網路;它們應位於單獨的管理網路上。將 iDRAC 放置或直接連線至網際網路,可能會使連線系統面臨安全性和其他風險,Dell 概不負責。   
  • 除了將 iDRAC 放置在個別管理子網路上,使用者也應使用防火牆等技術隔離管理子網路/vLAN,並限制只有經過授權的伺服器系統管理員才能存取子網路/vLAN。
  • Dell Technologies 建議客戶考慮可能與其環境相關的任何部署因素,以評估其整體風險。
