by CIRT Team
DESCRIPTION
Multiple vulnerabilities have been discovered in SAP products, the most severe of which could allow an unauthenticated, remote attacker to execute code on the affected systems. Details of the vulnerabilities are as follows:
* Multiple Vulnerabilities in SAP NetWeaver AS JAVA (LM Configuration Wizard) (CVE-2020-6286).
* Security updates for the browser control Google Chromium delivered with SAP Business Client.
* Information Disclosure in SAP NetWeaver (XMLToolkit for Java) (CVE-2020-6285).

* Information Disclosure in SAP NetWeaver (ABAP Server) and ABAP Platform (CVE-2020-6280).
IMPACT
Successful exploitation of the most severe of these vulnerabilities could allow an unauthenticated, remote attacker to execute code on the affected systems. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Applications configured to have fewer restrictions on the system could be less impacted than those who operate with elevated privileges.

RECOMMENDATIONS
The following actions are recommended:
* Apply appropriate updates provided by SAP to vulnerable systems, immediately after appropriate testing.
* Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
* Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
* Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
* Apply the Principle of Least Privilege to all systems and services.
