The Oracle PREPARE_UNBOUNDED_VIEW 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 PREPARE_UNBOUNDED_VIEW 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 SYS.DBMS_CDC_ISUBSCRIBE package to exploit this vulnerability.

Based on research into public information, we believe that this issue is Oracle vuln# DB06 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.
