Oracle DISABLE_HIERARCHY_INTERNAL procedure vulnerable to PL/SQL injection

Vulnerability Note VU#318764

Original Release Date: 2006-10-24 | Last Revised: 2006-10-24


The Oracle DISABLE_HIERARCHY_INTERNAL procedure is vulnerable to PL/SQL injection. This vulnerability may allow a remote, authenticated attacker to execute arbitrary PL/SQL commands on a vulnerable Oracle installation.


The Oracle DISABLE_HIERARCHY_INTERNAL procedure fails to properly filter user input allowing PL/SQL injection to occur. Note that an attacker must have execute privileges on the XDB.DBMS_XDBZ package to exploit this vulnerability.

Based on research into public information, we believe that this issue is Oracle vuln# DB15 in the October 2006 Oracle CPU. However, there is not sufficient information to authoritatively relate Oracle vulnerability information to information provided by other parties.


A remote attacker may be able to execute arbitrary PL/SQL queries on a server, possibly with elevated privileges. As a result, attackers may be able to view or modify the contents of an Oracle database.
