Description
Service names may be discovered by unauthenticated users. If the service name includes version numbers or other database product information, a malicious user may use that information to develop a targeted attack.
ℹ️ Check
If using a non-CDB database:
From SQL*Plus:
select instance_name, version from v$instance;
If using a CDB database:
To check the container database (CDB):
From SQL*Plus:
select instance_name, version from v$instance;
To check the pluggable databases (PDBs) within the CDB:
select name from v$pdbs;
Check Instance Name:
If the instance name returned references the Oracle release number, this is a finding.
Numbers used that include version numbers by coincidence are not a finding.
The database administrator (DBA) should be able to relate the significance of the presence of a digit in the SID.
✔️ Fix
Follow the instructions in Oracle MetaLink Note 15390.1 (and related documents) to change the SID for the database without recreating the database to a value that does not identify the Oracle version.
