XWiki vulnerable to Code Injection in template provider administration
Impact
Any user with edit rights on any document (e.g., the own user profile) can execute code with programming rights, leading to remote code execution by following these steps:
- Set the title of any document you can edit (can be the user profile) to
{{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
- Use the object editor to add an object of type
XWiki.TemplateProviderClass
(named "Template Provider Class") to that document. - Go to another document you can view (can be the home page) and append
?sheet=XWiki.AdminTemplatesSheet
to the URL.
When the attack is successful, a template with name "Hello from groovy!" is displayed in the list while on fixed systems, the full title should be displayed.
Patches
This vulnerability has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1.
Workarounds
The vulnerability can be fixed by patching the code in the affected XWiki document as shown in the patch.
