pysap is an open source Python library that provides modules for crafting and sending packets using SAP's NI, Diag, Enqueue, Router, MS, SNC, IGS, RFC and HDB protocols.
SAP Netweaver and
SAP HANA are technology platforms for
building and integrating SAP business applications. Communication between components
uses different network protocols and some services and tools make use of custom file
formats as well. While some of them are standard and well-known protocols, others
are proprietaries and public information is generally not available.
pysap
is an open source Python 2 library that provides modules for crafting and sending packets
using SAP's NI, Diag, Enqueue, Router, MS, SNC, IGS, RFC and HDB
protocols. In addition, support for creating and parsing different proprietary file
formats is included. The modules are built on top of Scapy and are
based on information acquired at researching the different protocols, file formats
and services.
Features
Dissection and crafting of the following network protocols:
SAP Network Interface (NI)
SAP Diag
SAP Enqueue
SAP Router
SAP Message Server (MS)
SAP Secure Network Connection (SNC)
SAP Internet Graphic Server (IGS)
SAP Remote Function Call (RFC)
SAP HANA SQL Command Network (HDB)
Client interfaces for handling the following file formats:
Library implementing SAP's LZH and LZC compression algorithms.
Automatic compression/decompression of payloads with SAP's algorithms.
Client, proxy and server classes implemented for some of the protocols.
Example scripts to illustrate the use of the different modules and protocols.
Installation
To install pysap simply run:
$ python -m pip install pysap
pysap is compatible and tested with Python 2.7.
Roadmap
Python 3 port project
⚠️ For legacy reasons, the project is only Python 2 compatible. There were some initial efforts to port the project to be Python 2 and 3 compatible, but those were never completed.
As time passed, and Python 2 started to loss relevance, we decided to start a new effort to complete the project and move the project to be Python 3 only compatible. The main reason is to avoid the introduction of backwards compatibility libraries that add complexity to the code and are not relevant in the current state of the Python project.
This project is actively being worked on right now by the OWASP CBAS project as part of the master-0.2 branchand tracked as a project.
This library is distributed under the GPLv2 license. Check the COPYING
file for more details.
Authors
he tool was initially designed and developed by Martin Gallo wile working at
SecureAuth's Innovation Labs team, with the
help of many contributors. The code was then contributed by SecureAuth to the
OWASP CBAS Project in October 2022.
The spirit of this Open Source initiative is to help security researchers,
and the community, speed up research and educational activities related to
the implementation of networking protocols and stacks.
The information in this repository is for research and educational purposes
only and is not intended to be used in production environments and/or as part
of commercial products.
If you desire to use this tool or some part of it for your own uses, we
recommend applying proper security development life cycle and secure coding
practices, as well as generate and track the respective indicators of
compromise according to your needs.
