-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SQL Injection in CREATE_SCN_CHANGE_SET procedure AppSecInc Team SHATTER Security Advisory http://www.appsecinc.com/resources/alerts/oracle/2005-05.html April 18, 2005 Affected versions: Oracle Database Server version 10g Risk level: High Credits: This vulnerability was discovered and researched by Esteban Martínez Fayó of Argeniss for Application Security Inc. Details: The CHANGE_SET_NAME parameter of the standard procedure SYS.DBMS_CDC_IPUBLISH.CREATE_SCN_CHANGE_SET is vulnerable to SQL injection. This procedure executes with privileges of the SYS user; by default, PUBLIC has EXECUTE privilege. Impact: Any low privileged database user can execute functions with DBA privileges. Users with privilges to create or modify a function can inject a user-defined function in the vulnerable procedure and thus execute SQL statements with DBA privileges. Workaround: Revoke Execute privilege on DBMS_CDC_IPUBLISH package. Vendor Status: Vendor was contacted and a patch was released.
