2416706 - Check file permissions for SAP HANA client hdbuserstore on application server


  • The data files of the hdbuserstore on Linux/Unix are sometimes (depending on the installer) world-readable (file permissions644,  -rw-r--r--).
    Affected files are "SSFS_HDB.DAT" and "SSFS_HDB.KEY".
    By default these files are protected by the directory privileges which are set to 700 (drwx------).
    That means, only the owner of the directory can access theses files – independent of the broader file permission.
  • Depending on installers, system configuration, and directory permissions, the directory and the files may get world-readable.
    That means a local user on the operating system could use the data files content and gain unauthorized access to the HANA DB.
