思科 IOS&IOS XE Software CMP遠端代碼執行漏洞通報

2017年3月17日美國時間下午4點，cisco官方網站釋出cisco ios&ios xe software 叢集管理協定(cluster management protocol)存在遠端代碼執行漏洞。該漏洞目前為0day漏洞，危害等級高。該漏洞允許未授權通路,遠端攻擊者可以重新開機裝置和遠端執行代碼提升權限。

cisco ios是cisco的網際作業系統；是一個為網際互連優化的複雜的作業系統；也是一個與硬體分離的軟體體系結構，随網絡技術的不斷發展，可動态地更新以适應不斷變化的技術（軟體）。

根據fofa系統顯示，目前全球共有超過43萬個對外可以通路（僅為全球分布情況，非漏洞影響情況）。其中美國超過3分之一；中國使用量位列第二。該漏洞受影響裝置達到319種型号。

漏洞原理與危害

叢集管理協定（cluster management protocol）是叢集成員之間内部使用telnet來進行信号和指令控制的協定。該漏洞是由兩個因素構成:

未能限制使用cmp-specific telnet選項隻對内部,而是接受 telnet連接配接到任何一個受影響的裝置。

cmp-specific telnet的錯誤處理選項

cmp-specific telnet 選項是預設的，即使沒有出現在設定的叢集設定指令中。

攻擊者可以利用此漏洞通過發送畸形cmp-specific telnet選項，向受影響裝置建立一個telnet會話。漏洞可能允許遠端攻擊者執行任意代碼,提升權限，完全控制受影響的裝置或導緻裝置重新開機。

影響範圍

修複建議

使用者可通過登入進入cisco ios系統，輸入show version檢查對應版本是否受影響。大緻内容如下：

另外也可以打開官方網站進行版本檢測，位址

修複方法

修改配置，設定telnet允許指定ip可以連接配接或者不允許telnet連接配接；
