The Oracle ENABLE_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 ENABLE_HIERARCHY_INTERNAL procedure fails to properly sanitize user input. This may allow a remote attacker to insert arbitrary SQL commands that may be executed by the database. Note that an attacker must have execute privileges on XDB.DBMS_XDBZ package to exploit this vulnerability.
Based on research into public information, we believe that this issue is Oracle vuln# DB01 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 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.
This vulnerability was reported in the Oracle Critical Patch Update for October 2006.
