Risk specificationIn certain situations, SAP Adaptive Server Enterprise allows a user with regular user credentials and local access to an ASE Cockpit installation to view unauthorized information that appears in the installation log. The log exists in the format of a file on the file system of the host.
In the patched version of SAP ASE Installer, the encrypted information is removed from the installation log file. And the good news are: a workaround exists, too! This was suggested by the SAP security experts: "In case you are using the affected versions then remove the installation log file from your setup."
