SAP GUI for Windows and SAP GUI for Java - versions SAP_BASIS 755, SAP_BASIS 756, SAP_BASIS 757, SAP_BASIS 758, allow an unauthenticated attacker to access information which would otherwise be restricted and confidential. In addition, this vulnerability allows the unauthenticated attacker to create Layout configurations of the ABAP List Viewer and with this causing a mild impact on integrity and availability, e.g. also increasing the response times of the AS ABAP.

Weakness

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

Potential Mitigations

  • Run the code in a “jail” or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
  • OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
