### Impact The HTML sanitizer, introduced in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid data attributes. This can be exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki: ``` [[Link1>>https://XWiki.example.com||data-x/onmouseover="alert('XSS1')"]]. ``` When a user moves the mouse over this link, the malicious JavaScript code is executed in the context of the user session. When this user is a privileged user who has programming rights, this allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. Note that this vulnerability does not affect restricted cleaning in HTMLCleaner as there attributes are cleaned and thus characters like `/` and `>` are removed in all attribute names. ### Patches This problem has been patched in XWiki 14.10.4 and 15.0 RC1 by making sure that data attributes only c...

### Impact It's possible to execute javascript with the right of any user by leading him to a special URL on the wiki targeting a page which contains an attachment. To reproduce: * add an attachment to a page (for example, your user profile) * add `?xpage=importinline&editor=%22%3E%3Cimg%20src%20onerror=alert(document.domain)%3E` to the page view URL as in `https://myhost/xwiki/bin/view/XWiki/MyUser?xpage=importinline&editor=%22%3E%3Cimg%20src%20onerror=alert(document.domain)%3E` ### Patches This has been patched in XWiki 15.0-rc-1, 14.10.4 and 14.4.8. ### Workarounds The easiest is to edit file `<xwiki app>/templates/importinline.vm` and apply the modification described on https://github.com/xwiki/xwiki-platform/commit/28905f7f518cc6f21ea61fe37e9e1ed97ef36f01 ### References https://jira.xwiki.org/browse/XWIKI-20340 https://app.intigriti.com/company/submissions/e95a7ad5-7029-4627-abf0-3e3e3ea0b4ce/XWIKI-E93DFEYK ### Attribution This vulnerability has been reported on Intigrit...

Red Hat Security Advisory 2023-2458-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include buffer overflow, bypass, denial of service, double free, memory leak, null pointer, out of bounds read, privilege escalation, traversal, and use-after-free vulnerabilities.

DHIS2 Core contains the service layer and Web API for DHIS2, an information system for data capture. Starting in the 2.35 branch and prior to versions 2.36.13, 2.37.8, 2.38.2, and 2.39.0, when the Category Option Combination Sharing settings are configured to control access to specific tracker program events or program stages, the `/trackedEntityInstances` and `/events` API endpoints may include all events regardless of the sharing settings applied to the category option combinations. When this specific configuration is present, users may have access to events which they should not be able to see based on the sharing settings of the category options. The events will not appear in the user interface for web-based Tracker Capture or Capture applications, but if the Android Capture App is used they will be displayed to the user. Versions 2.36.13, 2.37.8, 2.38.2, and 2.39.0 contain a fix for this issue. No workaround is known.
