A vulnerability in IBM DB2 for Linux, UNIX, and Windows could allow an authenticated user holding EXPLAIN authority to temporarily gain SELECT, INSERT, UPDATE or DELETE privilege on a table.
VULNERABILITY DETAILS:
CVE ID:CVE-2013-4033
IBM InfoSphere Balanced Warehouse C3000, C4000, and D5100 systems and IBM Smart Analytics System 1050, 2050, 5600, 5710, 7600, 7700, and 7710 systems are shipped with either IBM DB2 for Linux, UNIX, and Windows Version 9.7 or Version 10.1. There is a security vulnerability that could allow an authenticated user to temporarily gain SELECT, INSERT, UPDATE or DELETE privileges on a table. To exploit the vulnerability, the user would need to have a valid security credential to connect to the database and EXPLAIN, SQLADM, or DBADM authority. For more information, see: Security Bulletin: Unauthorized Access to Table Vulnerability in DB2 (CVE-2013-4033).
Under unspecified conditions, a user with EXPLAIN, SQLADM, or DBADM authority can execute a DML statement such as SELECT, INSERT, UPDATE and DELETE on a table that they do not have DATAACCESS authority for. Only DML statements are vulnerable.
The following query shows which user has EXPLAIN, SQLADM, or DBADM authority but no DATAACCESS authority:
SELECT
SUBSTR(grantor,1,10) grantor,
SUBSTR(grantee,1,20) grantee,
granteetype,
explainauth,
dbadmauth,
sqladmauth,
dataaccessauth
FROM SYSCAT.DBAUTH
WHERE
dataaccessauth = 'N' and
(explainauth = 'Y' or dbadmauth = 'Y' or sqladmauth = 'Y')
