The Oracle SQL92_SECURITY parameter must be set to TRUE.


Finding ID Version Rule ID IA Controls Severity

The configuration option SQL92_SECURITY specifies whether table-level SELECT privileges are required to execute an update or delete that references table column values. If this option is disabled (set to FALSE), the UPDATE privilege can be used to determine values that should require SELECT privileges. The SQL92_SECURITY setting of TRUE prevents the exploitation of user credentials with only DELETE or UPDATE privileges on a table from being able to derive column values in that table by performing a series of update/delete statements using a where clause, and rolling back the change. In the following example, with SQL92_SECURITY set to FALSE, a user with only delete privilege on the scott.emp table is able to derive that there is one employee with a salary greater than 3000. With SQL92_SECURITY set to TRUE, that user is prevented from attempting to derive a value. SQL92_SECURITY = FALSE SQL> delete from scott.emp where sal > 3000; 1 row deleted SQL> rollback; Rollback complete SQL92_SECURITY = TRUE SQL> delete from scott.emp where sal > 3000; delete from scott.emp where sal > 3000 * ERROR at line 1: ORA-01031: insufficient privileges

Fix Text (F-21542r533036_fix)
Enable SQL92 security.

From SQL*Plus:

alter system set sql92_security = TRUE scope = spfile;

The above SQL*Plus command will set the parameter to take effect at next system startup.
