Multiple SQL Injection Vulnerabilities in DBMS_CDC_SUBSCRIBE and
DBMS_CDC_ISUBSCRIBE Packages
------------------------------------------------------------------------
SUMMARY
The SUBSCRIPTION_NAME parameter -- used in various procedures of
SYS.DBMS_CDC_SUBSCRIBE and SYS.DBMS_CDC_ISUBSCRIBE packages -- is
vulnerable to SQL injection. These packages execute with privileges of the
SYS user; by default, PUBLIC has EXECUTE privilege.
DETAILS
Vulnerable Systems:
* Oracle Database Server version 10g
Impact:
Any low privileged database user can execute functions with DBA
privileges. Users with privileges 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 the vulnerable packages.
Vendor Status:
Vendor was contacted and a patch was released.
Fix:
Apply Oracle Critical Patch Update April 2005 available at:
<http://metalink.oracle.com>; http://metalink.oracle.com,
