Dangers in SAP® Transport Management Part 4: Automated Code Execution while Importing

December 7, 2017 From Thomas Fritsch, Virtual Forge GmbH

Almost every SAP® Basis administrator knows how dangerous XPRA entries can be in transport requests (R3TR XPRA <report name>). In principle, any report that does not require any specific parameters can be executed immediately after importing it. If the desired report is not available in the target system yet, it can either be imported with the same request or imported with a previous transport request. The later method is better for covering up attacks as the immediate connection between planting the code and executing it is not as easy to detect.

Dangers in SAP® Transport Management Part 2: Circumventing AUTHORITY CHECKS transaction-specifically

November 2, 2017 From Thomas Fritsch, Virtual Forge GmbH

The first article of this series talked about the global deactivation of authorization checks for single authorization objects per transport. A similar risk results from the possibility of deactivating authorization checks transaction-specifically. It is even more difficult to detect an attack if this method is used, as the impact can be limited to one transaction.

Dangers in SAP Transport Management Part 1: Circumventing AUTHORITY CHECKS

October 11, 2017 From Thomas Fritsch, Virtual Forge GmbH

The opinions on the SAP® authorization concept diverge widely. Surely, a certain complexity and the related maintenance effort cannot be denied. Yet, the most important requirement, the gapless protection of all read and write accesses within a program, can be realized quite well – at least in theory. In practice, there are several options to circumvent authorization checks.

If you have heard of the SAP Gateway, you should read this.

October 4, 2017 From Virtual Forge GmbH

It's amazing that this vulnerability was published as late as 2012, considering the fact that the SAP gateway is a standard interface for every SAP system. And specifically interfaces should be secured by all means. Eventually it was SAP themselves, which had drawn attention to the SAP Gateway Exploit. One of the most dangerous weaknesses of each SAP system is thus recognized - but still not secured at many SAP customers.

Take the First Step towards Higher Security with SAP® Penetration Tests

September 25, 2017 From Peter Maier-Borst, Virtual Forge GmbH

If you want to check if the doors of a house are securely locked, it is best to try it yourself. The resident has an advantage over an intruder: he knows all doors and windows which can be used or misused as entry points. The same holds true for SAP systems: a penetration test is far more effective if an external attack (black box pen-testing) is combined with an analysis of possible vulnerabilities from within (white box pen-testing).

Small solution – big impact

September 12, 2017 From Virtual Forge GmbH

Just like in life, small things can have a big impact on SAP development. For example, the quality of the customer’s code naturally depends on several factors, like the correct interception of exceptions, the use of sufficient comments, and making sure that database access does not unnecessarily waste any resources. But if one takes a closer look at customers’ development guidelines, one often finds a passage dictating naming conventions. Applying these naming conventions to all objects is not an easy task though.
