> **For authorized security testing only.** This project is intended for educational purposes, penetration testing, and security research on systems you own or have explicit permission to test.
## Overview
CVE-2025-53770 is a critical vulnerability in Microsoft SharePoint Server that allows unauthenticated remote code execution through a combination of authentication bypass and unsafe deserialization. This vulnerability affects SharePoint Server 2019 and is particularly dangerous as it requires no authentication.
The vulnerability chain includes:
- **CVE-2025-49706** - Authentication bypass affecting ToolPane.aspx
- **CVE-2025-53771** - Patch bypass for CVE-2025-49706
- **CVE-2025-49704** - Unsafe deserialization vulnerability
- **CVE-2025-53770** - Patch bypass targeting different endpoints
## Features
- **Multiple exploitation methods** - Python and cURL implementations
- **Target scanning** - Automated vulnerable version detection
- **Payload analysis** - Tools to decode and analyze exploit payloads
- **Comprehensive documentation** - Detailed vulnerability analysis and exploitation guidance
- **Real-world testing** - Proven against multiple SharePoint versions
## Getting started
### Prerequisites
- **Python 3.x** with `requests` and `urllib3` libraries
- **Network access** to target SharePoint servers
- **Authorization** to test target systems
## Usage
### Scanning for vulnerable targets
Use the scanner to identify potentially vulnerable SharePoint installations:
```bash
python3 scanner/scanner.py
```
### Running the exploit
#### Python exploitation
Execute the main Python exploit against a target:
```bash
python3 exploit/exploit.py
```
Example output:
```
[+] Targeting: http://192.168.1.100
[+] Sending exploit payload...
[+] Response Status: 200
[+] Response Length: 1234 bytes
```
#### cURL testing
Test using the provided cURL commands:
```bash
# Review the cURL file for specific commands
cat metasploit_ref/cURL
```
### Analyzing responses
Use the analysis tool to decode and examine exploit responses:
```bash
python3 analysis/analyse.py
```
This tool extracts and decodes base64-encoded payloads from captured traffic.

## Vulnerable versions
The following SharePoint Server versions are confirmed vulnerable:
- SharePoint Server 2019 `16.0.10337.12109` (RTM version)
- SharePoint Server 2019 `16.0.10417.20018` (June 2025 patch level)
- SharePoint Server 2019 `16.0.10417.20027` (July 2025 patch level)*
*The July 2025 patch level may still be exploitable unless administrators have manually performed configuration updates.
