#vulnerability

### Impact Any user with edit right on any page can perform arbitrary remote code execution by adding instances of `XWiki.SearchSuggestConfig` and `XWiki.SearchSuggestSourceClass` to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an instance, as a user without script nor programming rights, add an object of type `XWiki.SearchSuggestConfig` to your profile page, and an object of type `XWiki.SearchSuggestSourceClass` as well. On this last object, set both `name` and `icon` properties to `$services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')")` and `limit` and `engine` to `{{/html}}{{async}}{{velocity}}$services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')"){{/velocity}}{{/async}}`. Save and display the page. If the logs contain any message `ERROR ...

### Impact When uploading an attachment with a malicious filename, malicious JavaScript code could be executed. This requires a social engineering attack to get the victim into uploading a file with a malicious name. The malicious code is solely executed during the upload and affects only the user uploading the attachment. While this allows performing actions in the name of that user, it seems unlikely that a user wouldn't notice the malicious filename while uploading the attachment. In order to reproduce, as any user, create a file named `"><img src=1 onerror=alert(1)>.jpg`. Then go to any page where you have edit rights and upload the file in the attachments tab. If alerts appear and display "1", then the instance is vulnerable. ### Patches This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0. ### Workarounds We're not aware of any workaround except upgrading. ### References * https://jira.xwiki.org/browse/XWIKI-19611 * https://jira.xwiki.org/browse/XWIKI-21769 * h...
