### 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...

Red Hat Security Advisory 2023-1817-01 - Network Observability 1.2.0 is an OpenShift operator that provides a monitoring pipeline to collect and enrich network flows that are produced by the Network observability eBPF agent. The operator provides dashboards, metrics, and keeps flows accessible in a queryable log store, Grafana Loki. When a FlowCollector is deployed, new dashboards are available in the Console. This update contains bug fixes. Issues addressed include a denial of service vulnerability.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. 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. 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 creat...

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit rights on any document (e.g., their own user profile) can execute code with programming rights, leading to remote code execution. This vulnerability has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. If guest has view right on any document. It's possible to create a new user using the `distribution/firstadminuser.wiki` in the wrong context. This vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.1. There is no known workaround other than upgrading.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with view rights on `XWiki.AttachmentSelector` can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping in the "Cancel and return to page" button. This page is installed by default. This vulnerability has been patched in XWiki 15.0-rc-1, 14.10.1, 14.4.8, and 13.10.11. There are no known workarounds for this vulnerability.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The office document viewer macro was allowing anyone to see any file content from the hosting server, provided that the office server was connected and depending on the permissions of the user running the servlet engine (e.g. tomcat) running XWiki. The same vulnerability also allowed to perform internal requests to resources from the hosting server. The problem has been patched in XWiki 13.10.11, 14.10.1, 14.4.8, 15.0-rc-1. Users are advised to upgrade. It might be possible to workaround this vulnerability by running XWiki in a sandbox with a user with very low privileges on the machine.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. A registered user can perform remote code execution leading to privilege escalation by injecting the proper code in the "property" field of an attachment selector, as a gadget of their own dashboard. Note that the vulnerability does not impact comments of a wiki. The vulnerability has been patched in XWiki 13.10.11, 14.4.8, 14.10.2, 15.0-rc-1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
