*The most critical issues found by other researchers*


Some of our readers and clients asked us to categorize the most critical
SAP vulnerabilities to patch them first. Companies providing SAP Security
Audit, SAP Security Assessment, or SAP Penetration Testing services can
include these vulnerabilities in their checklists. The most critical
vulnerabilities of this update can be patched by the following SAP Security
Notes:



   - 2037304: <https://service.sap.com/sap/support/notes/2037304> SAP ST-P
   has a Remote Command Execution vulnerability (CVSS Base Score: 8.5). An
   attacker can use Remote Command Execution to run commands remotely.
   Executed commands will run with the privileges of the service that executes
   them. An attacker can access arbitrary files and directories located in an
   SAP server filesystem, including application source code, configuration,
   and critical system files. It allows obtaining critical technical and
   business-related information stored in the vulnerable SAP system. It is
   recommended to install this SAP Security Note to prevent risks.

   NetWeaver AFP Servlet has a Reflected File Download vulnerability (CVSS
   Base Score: 7.5). Reflected File Download (RFD) is a web attack vector
   that enables attackers to gain complete control over a victim's machine. In
   an RFD attack, the user follows a malicious link to a trusted domain
   resulting in a file download from that domain. It is recommended to install
   this SAP Security Note to prevent risks.
   - 2175928 <https://service.sap.com/sap/support/notes/2175928>: SAP HANA
   has a Running Process Remote Termination vulnerability (CVSS Base Score:
   6.8). An attacker can use this vulnerability to terminate the process of
   a vulnerable component. Nobody will be able to use this service, which has
   a negative impact on business processes, system downtime, and business
   reputation. It is recommended to install this SAP Security Note to prevent
   risks.

   integrity. It is recommended to install this SAP Security Note to prevent
   risks.


It is highly recommended to patch all those SAP vulnerabilities to prevent
business risks affecting your SAP systems.
