Missing authorization check in FM PRGN_INTERFACE_USER, SAP security note 1406435


The function modules SUPRN_INS_OR_DEL_PROFILE and PRGN_INTERFACE_USER (that are intended for internal use) allow you to avoid the authorization check of the user management.
The module PRGN_INTERFACE_USER contains a parameter for controlling the necessity of the authorization check.
If this parameter is not set, authorization profiles can be added to a user, although the executing user does not have the required authorizations for the user management.  The function module SUPRN_INS_OR_DEL_PROFILE uses this feature.
As a result, you can assign authorizations to yourself or other users for which you have no authorizations.
Such a use is not possible in the standard programs provided by SAP. However, if you call the modules using this option in customer-specific programs or using transaction SE37 in test mode, it is possible to avoid existing authorization concepts.
