CVE-2024-58319
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA reflected cross-site scripting vulnerability in Kentico Xperience allows attackers to inject malicious scripts via the Pages dashboard widget configuration dialog. Attackers can exploit this vulnerability to execute malicious scripts in administrative users' browsers.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA reflected cross-site scripting vulnerability exists in Kentico Xperience's Pages dashboard widget configuration dialog. The vulnerability allows unauthenticated attackers to inject malicious JavaScript code through crafted URLs or form inputs. When an authenticated administrative user interacts with the malicious payload, the script executes within their browser session, potentially allowing session hijacking or administrative actions performed on behalf of the victim.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Kentico Xperience installationCheck for Kentico Xperience by examining the application binaries, DLL files (such as CMS.dll or Kentico.Xperience.dll), or the presence of Kentico-related folders in the web root directory.Affected if The application is running Kentico Xperience CMS.
-
Identify installed versionLocate the version information in the Kentico Xperience installation. Common locations include: the CMS_UI/virtualized.xml or version.txt file in the installation directory, the AssemblyInfo.cs file, or by accessing the About page in the administration interface (typically at /CMSPages/About.aspx or through the Settings > Version info section).Affected if The installed version is 13.0.160 or lower.
-
Verify Pages dashboard widget is accessibleNavigate to the Pages application in the Kentico Xperience admin interface and verify the dashboard widget functionality is available. Check if the URL path /CMSModules/Content/CMSDesk/ contains the Pages-related modules.Affected if The Pages dashboard and its widget configuration dialog are accessible to authenticated administrators.
-
Inspect widget configuration dialog endpointExamine the web application's routing and handlers for the widget configuration dialog. Look for ASPX pages or handlers under paths related to CMSDesk, Pages, or widget configuration (such as /CMSModules/Widgets/ or similar). Check the page source for any unencoded user input reflection.Affected if The widget configuration dialog processes URL parameters or form inputs without proper encoding.
-
Review HTTP response for reflected parametersUsing browser developer tools or a web proxy, submit test parameters to the Pages dashboard widget configuration dialog and inspect the HTTP response to verify if input is reflected back in the response without encoding.Affected if User-supplied parameters appear unencoded in the HTTP response.
You are affected if Kentico Xperience version 13.0.160 or lower is installed and the Pages dashboard widget configuration dialog is accessible to authenticated administrative users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement contextual output encoding and input validation for all user-supplied data in the Pages dashboard widget configuration dialog. Apply Content Security Policy (CSP) headers to mitigate XSS execution. For immediate mitigation, consider restricting access to the affected functionality or deploying a WAF rule.
