SQL Injection in Oracle Database CREATE_CHANGE_SET procedure

Oct. 13 2010

Affected versions:
Oracle Database Server version 10gR1, 10gR2, 11gR1 and 11gR2

Remote exploitable:
Yes (Authentication to Database Server is needed)

Credits:
This vulnerability was discovered and researched by Esteban Martínez Fayó of Application Security Inc.

Details:
Oracle Database provides the DBMS_CDC_PUBLISH PL/SQL package owned by SYS that is part of the Change Data Capture 
component. This package has a SQL Injection vulnerability in CREATE_CHANGE_SET procedure. A malicious user can call the 
vulnerable procedure of this package with specially crafted parameters and execute SQL statements with the elevated 
privileges of the SYS user.

Impact:
To exploit this vulnerability EXECUTE permission on the SYS.DBMS_CDC_PUBLISH package is required. By default users 
granted the EXECUTE_CATALOG_ROLE role have this permission granted. Exploitation of this vulnerability allows an 
attacker to execute SQL commands with SYS privileges.

Vendor Status:
Vendor was contacted and a patch was released.

Workaround:
Restrict access to the SYS.DBMS_CDC_PUBLISH package.

Fix:
Apply Oracle Critical Patch Update October 2010 available at Oracle Metalink.
