This is certainly akin to every one of the documents with a UNIX OS becoming SUID by default. Hence a quite common method of gaining complete control of an Oracle database is to get a very low privileged account by using a weak password and escalate privilege to DBA via PLSQL injections like the one particular over.
For that reason, all messages originating Within the set off that would ordinarily get to the person, like error messages and messages in the PRINT statement, are diverted on the SQL ServerSQL Server mistake log.
