 SAP Network Topology Scanner 
 The scanner that speaks SAPanese 
 Fluent in DIAG &middot; RFC &middot; Gateway &middot; MS &middot; ICM &middot; J2EE &middot; BTP Cloud

by <a href="https://github.com/kloris">Joris van de Vis</a>

---

SAPology is an **SAP security testing tool** for discovering, fingerprinting, and assessing SAP systems on a network. It combines port scanning, protocol-level fingerprinting (DIAG, RFC, Gateway, Message Server, ICM, SAPControl), and vulnerability assessment into a single self-contained scanner. It also includes a **BTP Cloud Scanner** for discovering and assessing SAP Business Technology Platform services exposed on the internet.

## Features

- **Two-phase discovery** - Quick pre-scan identifies SAP hosts, full scan enumerates all services
- **Protocol fingerprinting** - Native parsing of SAP DIAG, RFC, Gateway, Message Server, ICM, P4, and SAP Router protocols
- **SAPControl interrogation** - Extracts SID, kernel version, instance details, and system topology via SOAP
- **RFC system enrichment** - Unauthenticated RFC_SYSTEM_INFO probing to extract OS, database type, SAP release, hostname, and kernel version from ABAP systems
- **Client enumeration** - DIAG-based enumeration of SAP clients (000-999) with automatic client redirection detection for S/4HANA systems
- **Default credential check** - Opt-in testing of 16 well-known SAP default user/password combinations via DIAG login, with stop-on-lock protection to minimize account lockout risk
- **System type detection** - Identifies ABAP, Java, ABAP+Java, BusinessObjects, Cloud Connector, Content Server, SAP Router, MDM, and HANA systems
- **Vulnerability assessment** - Checks for 15+ CVEs and misconfigurations including unprotected gateways (SAPXPG), open Message Server ports, HTTP smuggling, exposed admin consoles, SSL/TLS weaknesses, and HTTP verb tampering
- **ICM URL scanning** - Tests 1,600+ SAP-specific URL paths per HTTP port for exposed endpoints
- **Hail Mary mode** - Scans all RFC 1918 private subnets (~17.9M IPs) using async two-phase subnet sweeping, or a user-supplied subset via `--hm-ranges`
- **Known inventory mode** - Feed a CSV of already-known SAP systems (`--inventory`); discovered systems are tagged known/unknown in the report so shadow or unmanaged SAP stands out. Optional `--inventory-skip` removes known systems from the report entirely for focused discovery.
- **BTP Cloud Scanner** - Discovers and assesses SAP BTP subaccounts, Cloud Foundry apps, XSUAA, CPI, and other cloud services via CT logs, DNS, Shodan, Censys, and Wayback Machine
- **HTML & JSON reporting** - Rich interactive HTML reports and structured JSON exports
- **Desktop GUI** - Native desktop interface with real-time dashboard, severity charts, and findings browser
- **Windows standalone** - Pre-built `.exe` that runs without Python

## Quick Start

### Command-Line Scanner

```bash
# Scan a single target
python3 SAPology.py -t 192.168.1.100

# Scan a subnet with verbose output
python3 SAPology.py -t 10.0.0.0/24 -v

# Scan with HTML report output
python3 SAPology.py -t 192.168.1.0/24 -o report.html

# Scan from a target file, export JSON
python3 SAPology.py -T targets.txt --json results.json

# Skip vulnerability checks (discovery only)
python3 SAPology.py -t 192.168.1.100 --skip-vuln

# Check for default SAP credentials (opt-in, can lock accounts!)
python3 SAPology.py -t 192.168.1.100 --default-creds

# Hail Mary - scan all private subnets
python3 SAPology.py --hail-mary

# Hail Mary - scan only a specific internal range (focused assessment)
python3 SAPology.py --hail-mary --hm-ranges 10.50.0.0/16

# Hail Mary - scan multiple user-supplied CIDRs
python3 SAPology.py --hail-mary --hm-ranges 10.50.0.0/16,172.20.0.0/20,192.168.5.0/24

# Known-inventory mode: tag each discovered system as known/unknown
python3 SAPology.py -t 10.0.0.0/24 --inventory known_sap.csv

# Known-inventory mode: skip known systems entirely (focused discovery)
python3 SAPology.py -t 10.0.0.0/24 --inventory known_sap.csv --inventory-skip
```

#### Inventory CSV Format

The `--inventory` file is a plain CSV with 1-3 columns per row and `#` comments:

```
# known_sap.csv — fields: ip[,sid[,instance]]
10.10.1.5                # whole host known (any SID/instance)
10.10.2.38,AED           # any instance of SID AED on this IP is known
10.10.3.100,AEQ,00       # only this specific instance is known
10.10.3.100,AEQ,01       # and this one
```

In **tag mode** (default), everything is scanned and each result gets a
"Known" or "Unknown" pill in the HTML report plus counts in the executive
summary. In **skip mode** (`--inventory-skip`), known systems are removed
from the landscape before vulnerability assessment, so the report only
contains discoveries you didn't know about.

### BTP Cloud Scanner

```bash
# Scan a known BTP endpoint
python3 SAPology.py --btp-target myapp.cfapps.eu10.hana.ondemand.com

# Discover BTP subdomains via Certificate Transparency logs
python3 SAPology.py --btp-discover mycompany

# Scan a custom domain mapped to BTP
python3 SAPology.py --btp-target portal.mycompany.com

# Scan from a file of BTP endpoints
python3 SAPology.py --btp-targets btp_urls.txt

# BTP standalone mode (no SAPology.py needed)
python3 SAPology_btp.py -t myapp.cfapps.eu10.hana.ondemand.com
python3 SAPology_btp.py -d mycompany -o btp_report.html

# Combined on-prem + BTP scan
python3 SAPology.py -t 10.0.0.0/24 --btp-discover mycompany
```

### Standalone Tools

The `files/` directory contains standalone modules that can also be used independently:

```bash
# Enumerate SAP clients (000-999) via DIAG protocol
python3 files/sap_client_enum.py -t 192.168.1.100:3200
python3 files/sap_client_enum.py -t 192.168.1.100:3200 --range 0-100 -v

# Check default SAP credentials via DIAG login
python3 files/sap_default_creds.py -t 192.168.1.100:3200 -c 000,001,066
python3 files/sap_default_creds.py -t 192.168.1.100:3200 -c 000,001 -v

# Probe RFC_SYSTEM_INFO (unauthenticated system info retrieval)
python3 files/sap_rfc_system_info.py -t 192.168.1.100 -p 3300 -v
```

### Desktop GUI

```bash
# Launch with native window (pywebview)
python3 SAPology_gui.py

# Launch in your default web browser
python3 SAPology_gui.py --browser
```

### Windows Standalone

Download `SAPology.exe` from the [Releases](../../releases) page and run from Command Prompt:

```cmd
SAPology.exe -t 192.168.1.100
SAPology.exe -t 10.0.0.0/24 -v -o report.html
```

No Python installation required.

## Installation

### Command-Line Scanner Prerequisites

| Requirement | Notes |
|---|---|
| **Python** | 3.7 or later |
| **requests** | HTTP library (required) |
| **rich** | Terminal formatting (optional, for progress bars) |

```bash
pip install requests rich
```

That's it. The scanner is a single file with no other dependencies.

### GUI Prerequisites

The GUI requires additional packages on top of the scanner prerequisites:

| Requirement | Notes |
|---|---|
| **bottle** | Lightweight HTTP server for the Python-JS bridge |
| **pywebview** | Native desktop window (optional, falls back to browser) |

```bash
pip install requests rich bottle pywebview
```

**pywebview system dependencies (Linux):**

On Ubuntu/Debian, pywebview requires WebKit2GTK:

```bash
sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.0
```

If pywebview is not installed or fails to load, the GUI automatically falls back to opening in your default web browser. You can also force browser mode:

```bash
python3 SAPology_gui.py --browser
```

### Building the Windows Executable

To build `SAPology.exe` yourself on a Windows machine:

1. Install Python 3.8+ from [python.org](https://python.org)
2. Place `SAPology.py` and `build_windows.bat` in the same folder
3. Double-click `build_windows.bat`
4. The executable will be created in the `dist\` folder

The batch file installs PyInstaller and all dependencies automatically.

## Supported Operating Systems

| OS | CLI Scanner | GUI (native window) | GUI (browser mode) | Standalone .exe |
|---|---|---|---|---|
| **Linux** (Ubuntu 20.04+, Debian, Kali, etc.) | Yes | Yes (with WebKit2GTK) | Yes | - |
| **macOS** | Yes | Yes | Yes | - |
| **Windows 10/11** | Yes (with Python) | Yes | Yes | Yes |
| **Windows** (no Python) | - | - | - | Yes |

## BTP Cloud Scanning

The BTP Cloud Scanner (`SAPology_btp.py`) discovers and assesses SAP Business Technology Platform services exposed on the internet. It runs as a standalone tool or integrated into SAPology.

### BTP Scan Phases

1. **Discovery** — Find BTP endpoints via Certificate Transparency logs (crt.sh), DNS enumeration, Shodan, Censys, and Wayback Machine
2. **Fingerprinting** — HTTP probing with 25+ SAP-specific paths, header analysis, TLS inspection, Cloud Foundry SSH detection (port 2222)
3. **Vulnerability Assessment** — 17 security checks covering authentication, configuration exposure, CORS, transport security, and information disclosure
