XWiki Platform vulnerable to SQL injection through getdeleteddocuments.vm template sort parameter

Impact

It's possible for anyone to inject SQL using the parameter sort of the getdeleteddocuments.vm. It's injected as is as an ORDER BY value.

One can see the result of the injection with http://127.0.0.1:8080/xwiki/rest/liveData/sources/liveTable/entries?sourceParams.template=getdeleteddocuments.vm&sort=injected (this example does not work, but it shows that an HQL query was executed with the passed value which look nothing like an order by value, without any kind of sanitation).

Patches

This has been patched in 17.3.0-rc-1, 16.10.6.

Workarounds

There is no known workaround, other than upgrading XWiki.
