Impact
It's possible to execute any SQL query in Oracle by using the function like DBMSXMLGEN or DBMSXMLQUERY.
The XWiki query validator does not sanitize functions that would be used in a simple select and Hibernate allows using any native function in an HQL query.
Patches
This has been patched in 16.10.2, 16.4.7 and 15.10.16.
Workarounds
There is no known workaround, other than upgrading XWiki.
