Potential remote termination of running processes in ABAP & Java Server, SAP security note 2121661

SAP Note 2121661

SAP security note 2121661, “Potential Remote Termination of Running Processes in ABAP & Java Server”, is a note. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

An attacker can remotely exploit various components of ABAP and Java Server, as well as RFC-bound external components, potentially terminating running processes. This issue is caused by a memory corruption that leads the process to attempt reading outside its memory space, resulting in a memory protection fault. Consequently, the system terminates the process, rendering the application unusable until it is manually restarted.

Solution

To mitigate this vulnerability, apply the following updates:

  • SAP Kernel: Upgrade to a version equal to or higher than those specified in the Support Package Patches section.
  • jstart: Use a version as described in the Kernel patches section.
  • R3trans: Update to at least version 11.02.15 as per SAP Note 19466.
  • R3load: Upgrade to the version mentioned in SAP Note 2136942 and download from SAP Note 1724496.
  • SAP NetWeaver RFC SDK: Use at least version 7.21 PL 34 (SAP Note 1025361).
  • SAP Java Connector (JCo): Upgrade to at least JCo 3.0.13 (SAP Note 2155739).
  • SAP .NET Connector: Use version 3.0.15 or higher (SAP Note 2095394).
  • ABAP Development Tools for SAP NetWeaver: Upgrade to at least version 2.41 (SAP Note 2126477).
  • HANA Studio: Use at least HANA Studio 2.0.12, part of HDB 1.0 revision 94.

Ensure all relevant patches are applied to maintain system security and stability.
