思科 IOS&IOS XE Software CMP远程代码执行漏洞通报
作者:星期三, 三月 29, 20170

2017年3月17日美国时间下午4点,Cisco官方网站发布Cisco IOS&IOS XE Software 集群管理协议(Cluster Management Protocol)存在远程代码执行漏洞。该漏洞目前为0day漏洞,危害等级高。该漏洞允许未授权访问,远程攻击者可以重启设备和远程执行代码提升权限。

Cisco IOS是Cisco的网际操作系统;是一个为网际互连优化的复杂的操作系统;也是一个与硬件分离的软件体系结构,随网络技术的不断发展,可动态地升级以适应不断变化的技术(软件)。

根据FOFA系统显示,目前全球共有超过43万个对外可以访问(仅为全球分布情况,非漏洞影响情况)。其中美国超过3分之一;中国使用量位列第二。该漏洞受影响设备达到319种型号。

漏洞原理与危害

集群管理协议(Cluster Management Protocol)是集群成员之间内部使用TELNET来进行信号和命令控制的协议。该漏洞是由两个因素构成:

1. 未能限制使用CMP-specific Telnet选项只对内部,而是接受 Telnet连接到任何一个受影响的设备。

2. CMP-specific Telnet的错误处理选项

CMP-specific Telnet 选项是默认的,即使没有出现在设置的集群设置命令中。

攻击者可以利用此漏洞通过发送畸形CMP-specific Telnet选项,向受影响设备建立一个Telnet会话。漏洞可能允许远程攻击者执行任意代码,提升权限,完全控制受影响的设备或导致设备重启。

影响范围

CVE编号

CVE-2017-3881

修复建议

用户可通过登录进入Cisco IOS系统,输入Show Version检查对应版本是否受影响。大致内容如下:

另外也可以打开官方网站进行版本检测,地址

https://tools.cisco.com/security/center/selectIOSVersion.x

修复方法

1. 修改配置,设置Telnet允许指定IP可以连接或者不允许Telnet连接;

2. 目前官方还未发布补丁,请时刻关注Cisco官方发布的补丁和最新更新。
