Impact

A user that doesn't have programming rights can execute arbitrary code when creating a page using the Migration Page template. A possible attack vector is the following:

• Create a page and add the following content:

• Use the object editor to add an object of type XWiki.TranslationDocumentClass with scope USER.
• Access an unexisting page using the MigrationTemplate

It is expected that {{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}} will be present on the page, however, hello from groovy will be printed.

Patches

The issue will be fixed as part of v1.2. The fix was added with commit 35cef22
