XWiki Platform vulnerable to privilege escalation (PR) from account through TipsPanel

Impact

It's possible to execute any wiki content with the right of the TipsPanel author by creating a tip UI extension.

To reproduce:

  • Add an object of type UIExtensionClass
  • Set "Extension Point ID" to org.xwiki.platform.help.tipsPanel
  • Set "Extension ID" to org.xwiki.platform.user.test (needs to be unique but otherwise doesn't matter)
  • Set "Extension Parameters" to 
    tip={{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
  • Set "Extension Scope" to "Current User".
  • Click "Save & View"
  • Open the "Help.TipsPanel" document at <xwiki-host>/xwiki/bin/view/Help/TipsPanel where <xwiki-host> is the URL of your XWiki installation and press refresh repeatedly.

The groovy macro is executed, after the fix you get an error instead.
