發現時間	2017-03-21 00:00:00
發佈時間	2017-03-27 13:18:59
事故類型	ANA-漏洞預警
影響等級	中
主旨說明	【漏洞預警】Cisco IOS與IOS XE軟體中的叢集管理協定存在零時差漏洞(CVE-2017-3881)，導致攻擊者可遠端執行任意程式碼，進而取得設備控制權或重新啟動，請儘速確認並採取建議措施
內容說明	[內容說明]: 轉發行政法人國家資通安全科技中心 資安訊息警訊 NCCST-ANA-201703-0051 美國思科(Cisco)公司於今年3月得知國際名為維基解密(WikiLeaks)組織所釋出的Vault 7文件後，開始調查相關產品是否有受影響，並於3月17日公布發現一個波及318款網路交換機產品之零時差漏洞(CVE-2017-3881)。 該漏洞主要是Cisco IOS與IOS XE網路軟體的叢集管理協定(Cluster Management Protocol，CMP)未能有效限制可接受之Telnet連線來源，以及未能正確處理改造的Telnet指令，導致攻擊者可遠端執行任意程式碼，進而取得設備控制權限，或執行reload指令重新啟動設備。

建議措施	請各單位可聯絡設備維護廠商確認是否使用受影響之產品，則請參考以下建議資訊： 1.目前因Cisco官方尚未針對Cisco IOS與IOS XE釋出修復版本，所以仍請密切注意Cisco官方網頁(https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170317-cmp)之更新訊息。 2.停用Telnet連線機制，改採SSH連線機制，以降低風險。
