# API Reference: Insecure Deserialization Detection Agent
|
|
|
|
## Dependencies
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| requests | >=2.28 | HTTP requests for scanning cookies and responses |
|
|
| pickle | stdlib | Python pickle payload generation for testing |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python scripts/agent.py --url https://target.example.com/dashboard \
|
|
--callback oob.attacker.com --output deser_report.json
|
|
```
|
|
|
|
## Functions
|
|
|
|
### `detect_serialization_format(data) -> str`
|
|
Identifies serialization format from a string: `java_serialized`, `dotnet_viewstate`, `php_serialized`, `python_pickle`.
|
|
|
|
### `scan_cookies(url, session) -> list`
|
|
Fetches the URL and checks each response cookie value for serialization markers.
|
|
|
|
### `scan_response_body(url, method, data) -> list`
|
|
Scans the HTTP response body for Java Base64 (`rO0AB`), PHP serialized objects, and `__VIEWSTATE` fields.
|
|
|
|
### `test_java_deserialization(url, cookie_name, callback_host) -> dict`
|
|
Injects a URLDNS-style probe into a cookie to trigger DNS callback on deserialization.
|
|
|
|
### `test_php_deserialization(url, param_name) -> dict`
|
|
Sends PHP serialized object payloads attempting role escalation.
|
|
|
|
### `test_python_pickle(url, param_name, callback_host) -> dict`
|
|
Generates a pickle payload with `__reduce__` that triggers a DNS lookup for OOB detection.
|
|
|
|
### `run_assessment(url, callback_host) -> dict`
|
|
Orchestrates cookie and body scanning.
|
|
|
|
## Serialization Markers
|
|
|
|
| Format | Magic / Prefix | Example |
|
|
|--------|---------------|---------|
|
|
| Java binary | `\xac\xed\x00\x05` | Raw bytes |
|
|
| Java Base64 | `rO0AB` | Base64-encoded |
|
|
| .NET ViewState | `/wE` | `__VIEWSTATE` hidden field |
|
|
| PHP | `O:4:`, `a:2:` | Object/array notation |
|
|
| Python pickle | `\x80` (protocol byte) | Base64-encoded |
|
|
|
|
## Output Schema
|
|
|
|
```json
|
|
{
|
|
"target": "https://target.example.com/",
|
|
"serialized_data_found": 2,
|
|
"cookie_findings": [{"name": "session", "format": "java_serialized"}],
|
|
"formats_detected": ["java_serialized"]
|
|
}
