### Impact Any user who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening `/xwiki/bin/view/AppWithinMinutes/CreateApplication?wizard=true` on the XWiki installation. ### Patches This has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1 by not granting the space admin right if the user doesn't have script right on the space where the app is created. Error message are displayed to warn the user that the app will be broken in this case. Users who became space admin through this vulnerability won't loose the space admin right due to the fix, so it is advised to check if all users who created AWM apps should keep their space admin rights. ### Workarounds The patch can ...

### 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: 1. 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}} ``` 2. Use the object editor to add an object of type `XWiki.TemplateProviderClass` (named "Template Provider Class") to that document. 3. 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...

### Impact If a guest has view rights on any document, it's possible to create a new user using the `distribution/firstadminuser.wiki` in the wrong context. To reproduce: * On a wiki with view rights for guests but user registration disabled, open as guest <server>/xwiki/bin/view/Main?sheet=CKEditor.HTMLConverter&language=en&sourceSyntax=xwiki%2F2.1&stripHTMLEnvelope=true&fromHTML=false&toHTML=true&text=%7B%7Btemplate+name%3D%22distribution%2Ffirstadminuser.wiki%22+%2F%7D%7D where <server> is the URL of your XWiki installation. * Enter username and password of your choice. * Click "Register and login" ### Patches The vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.1. ### Workarounds There is no known workaround other than upgrading. ### References https://jira.xwiki.org/browse/XWIKI-19852 https://jira.xwiki.org/browse/XWIKI-20400 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwik...

### Impact Any user with edit rights on a page (e.g., it's own user page), 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 information loaded from attachments in `imported.vm`, `importinline.vm`, and `packagelist.vm`. This page is installed by default. Reproduction steps are described in https://jira.xwiki.org/browse/XWIKI-20267 ### Patches The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.1, 14.4.8, and 13.10.11. ### Workarounds The issue can be fixed by applying this [patch](https://github.com/xwiki/xwiki-platform/commit/e4bbdc23fea0be4ef1921d1a58648028ce753344) on `imported.vm`, `importinline.vm`, and `packagelist.vm`. ### References - https://github.com/xwiki/xwiki-platform/commit/e4bbdc23fea0be4ef1921d1a58648028ce753344 - https://jira.xwiki.org/browse/XWIKI-20267 ### For more information If you have any questions or comments about this advisory: * Open ...

### Impact The "restricted" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1 and massively improved in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid HTML comments. As a consequence, any code relying on this "restricted" mode for security is vulnerable to JavaScript injection ("cross-site scripting"/XSS). An example are anonymous comments in XWiki where the HTML macro filters HTML using restricted mode: ```html {{html}} <!--> <Details Open OnToggle=confirm("XSS")> {{/html}} ``` When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. Note that while all versions since 4.2-milestone-1 should be vulnerable, only starting with version 14.6-rc-1 the HTML comment is...

### Impact In XWiki, every user can add translations that are only applied to the current user. This also allows overriding existing translations. Such translations are often included in privileged contexts without any escaping which allows remote code execution for any user who has edit access on at least one document which could be the user's own profile where edit access is enabled by default. The following describes a proof of concept exploit to demonstrate this vulnerability: 1. Edit the user profile with the wiki editor and set the content to ``` error={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}} ``` 2. Use the object editor to add an object of type `XWiki.TranslationDocumentClass` with scope `USER`. 3. Open the document `WikiManager.AdminWikiDescriptorSheet`. The expected result would be that a message with title `{{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groo...
