The most critical vulnerabilities of this update can be patched by the following SAP Security Notes:

  • 2408892: SAP Netweaver Data Orchestration has a Missing Authorization Check vulnerability (CVSS Base Score: 8.5).

  • 2391018: SAP 3D Visual Enterprise Author, Generator and Viewer has a Memory Corruption vulnerability (CVSS Base Score: 8). An attacker can use a Buffer overflow vulnerability to inject a specially crafted code into a working memory that will be executed by the vulnerable application. Executed commands will run with the same privileges as the service that executed the command. This can lead to taking complete control of the application, denial of service, command execution, and other attacks. Install this SAP Security Note to prevent the risks.
  • Multiple vulnerabilities in SAP HANA (CVSS Base Score: 8.3). Update is available in SAP Security Note 2407694. An attacker can use a Denial of service vulnerability to crash a process of the vulnerable component. For this time, nobody would be able to use this service, which negatively influences business processes, system downtime, and, as a result, business reputation.
