XWiki Platform has an SQL injection in getdocuments.vm with sort parameter

Impact

In getdocument.vm ; the ordering of the returned documents is defined from an unsanitized request parameter (request.sort) and can allow any user to inject HQL.

Depending on the used database backend, the attacker may be able to not only obtain confidential information such as password hashes from the database, but also execute UPDATE/INSERT/DELETE queries.

It's possible to employ database backend dependent techniques of breaking out of HQL query context, described, for example, here: https://www.sonarsource.com/blog/exploiting-hibernate-injections.

Patches

This has been patched in 13.10.5 and 14.3-rc-1.

Workarounds

There is no known workaround, other than upgrading XWiki.
