[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2099) Support protection against SQL injection in Query order parameter

[ http://jira.jboss.com/jira/browse/JBSEAM-2099?page=comments#action_12382337 ] Diego Ballve commented on JBSEAM-2099: -------------------------------------- Felix, I agree this is getting more complex than ideal, but If you want more complex order you have more to change than just validating the order param. But lets go through the comments: First, backward compatibility is not broken. If list of valid params is not set, any is still acceptable. Second, I have not been using xml to set up queries, i needed more than what xml could offer.. but I agree It would be desirable to be able to set valid props from xml. Third: - more than one property: still simple, the check could verify that all props are in the valid list. And actually, I'm splitting the string on spaces, not commas.. 'e.lastname,e.firstname' would be seen as 1 prop.. if defined as valid, it would pass. ;) - order by child object: we actually use that, the trick is the property must appear in the select.. the way we solved it, your query would become: SELECT e, e.department.name as depName FROM Employee e ORDER BY e.department.name Besides, you need to say e.department.name is a valid order parameter and you need getResultList() to process the resulting.. if it is List<Object[]> then return a new List containing item[0].. Not pretty but did the trick. Not to loose focus, the root of the problem is not to allow anything coming from a mapped requestParam.order to make it to the HQL query, unchecked. If you can restrict what fields can be exposed to web user, even better. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
