高危 代码执行漏洞
CVE编号
CVE-2017-17405利用情况
POC 已公开补丁情况
官方补丁披露时间
2017-12-15漏洞描述
2.4.3之前的Ruby允许Net :: FTP命令注入。 Net :: FTP＃get，getbinaryfile，gettextfile，put，putbinaryfile和puttextfile使用Kernel＃open打开本地文件。如果localfile参数以“|”pipe character开头，执行 pipe character符后面的命令。 localfile的默认值是File.basename(remotefile)，因此恶意FTP服务器可能导致任意命令执行。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://www.ruby-lang.org/en/news/2017/12/14/ruby-2-4-3-released/受影响软件情况
