IT Security Isn’t Important! Right?

Table of Contents

As an IT manager or user, you have an obligation to act. Why? See for yourself:…

We are living in exciting times. Times that call for action as never before – both in a professional and personal context. One of the topics that amazingly is given short shrift all too often is IT security. After all, it’s not important. It will take care of itself. Just like updates. They’re sent out by the manufacturers automatically, aren’t they? But what does this mean exactly? Where is the sticking point?

The global IT environments are no longer based exclusively on physical machines in an in-house computing center. In fact, they are often no longer on company premises at all, or even in the same country. They are distributed all over in the computing centers of various providers. For that reason, opportunities abound for losing data, falling victim to attacks or losing access to parts of environments. But how can one overcome this challenge?

In our new Security Blog series – starting today, we would like to keep you informed about the latest security vulnerability and their updates. Further on, in a special series we will also explore new security topics in greater detail as part of ‘technical deep dives’.

In these we will cover the following developers: SAP, Microsoft, Citrix, VMWare, Pulse Secure, Juniper, IBM, Oracle, Suse & Avantra.

At the beginning of our series, you will gain an overview of the security vulnerabilities of the month of June 2021:


CVE-2021-27602 – Remote Code Execution Vulnerability

Base Score 9.9

Affected component: SAP Commerce

CVE-2021-27610 – Improper Authentication in SAP NetWeaver ABAP Server and ABAP Platform

Base Score 9.0

Affected component: SAP NetWeaver ABAP Server and ABAP platform

The ABAP Server does not differentiate as to whether communication via RFC or http is taking place between the application server in the same SAP environment or with a server outside the environment. Attackers are therefore able to read ‘credentials’ from internal communication. Multiple other attack scenarios are thus conceivable.

We recommend that you patch this vulnerability immediately!

CVE-2021-27635 – Missing XML Validation in SAP NetWeaver AS for Java

Base Score 8.7

Affected component: SAP NetWeaver AS for Java

This gap is critical, as the attack with an authenticated user is capable of connecting through the network as an administrator and injecting a prepared XML file. In this way the attacker can read any file in the system and in some cases even cause system failures.
