VLAI?
Summary
org.xwiki.platform:xwiki-platform-panels-ui vulnerable to Eval Injection
Details

Impact

Any user with view 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 UIX parameters

A proof of concept exploit is to log in, add an XWiki.UIExtensionClass xobject to the user profile page, with an Extension Parameters content of:

order=100
label={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
icon=icon:pencil
target=XWiki.username

Then, navigating to PanelsCode.ApplicationsPanelConfigurationSheet (i.e., <xwiki-host>/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet where <xwiki-host> is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see Hello from groovy! displayed on the screen.

Patches

The vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1

Workarounds

The issue can be fixed by editing the PanelsCode.ApplicationsPanelConfigurationSheet wiki page and making the same modifications as shown in the patch for this issue.
