      [SECURITY] Do not log stacktrace in exception handlers · fb542d43
      Torben Hansen authored
      When a TYPO3 exception is handled through registered exception
      handlers, log writers may log sensitive information to logs,
      since the full stacktrace is logged.
      
      With this change, exception handlers that extend
      AbstractExceptionHandler except DebugExceptionHandler will
      by default not include the exception object any more and
      thereby not log the full stacktrace.

      [SECURITY] Restrict export functionality to allowed users · f4dd6171
      Torben Hansen authored
      The import functionality of the import/export module is already
      restricted to admin users or users, who explicitly have access through
      the user TSConfig setting "options.impexp.enableImportForNonAdminUser".
      
      The export functionality has the following security drawbacks:
      
      * Export for editors is not limited on field level
      * The "Save to filename" functionality saves to a shared folder, which
        other editors with different access rights may have access to.
      
      Both issues are not easy to resolve and also the target audience for
      the Import/Export functionality are mainly TYPO3 admins.
      
      Therefore, now also the export functionality is restricted to TYPO3
      admin users and to users, who explicitly have access through the new
      user TSConfig setting "options.impexp.enableExportForNonAdminUser".
      
      Additionally, the contents of the temporary "importexport" folder in
      file storages is now only visible to users who have access to the
      export functionality.
      
      In general, it is recommended to only install the Import/Export
      extension when the functionality is required.
