CVE-2022-2511
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 · uneditedCross-site Scripting (XSS) vulnerability in the "commonuserinterface" component of BlueSpice allows an attacker to inject arbitrary HTML into a page using the title parameter of the call URL.
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 XSS vulnerability exists in the 'commonuserinterface' component of BlueSpice where the title parameter in the URL is not properly sanitized, allowing attackers to inject arbitrary HTML (including JavaScript) that gets rendered in the page context.

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.
-
Identify BlueSpice installation and versionLocate the BlueSpice version file or admin interface - typically found in the extension's version file, composer.json, or the BlueSpice admin dashboard under 'Version' or 'About' sectionsAffected if Installed version is lower than 4.1.3 (e.g., 4.1.0, 4.0.x, 3.x series)
-
Confirm commonuserinterface component is presentCheck for the 'commonuserinterface' component in the BlueSpice installation directory or via the admin interface component list - look for files or modules named 'commonuserinterface' or similarAffected if The commonuserinterface component exists and is enabled in the BlueSpice installation
-
Verify URL parameter handling for title parameterAccess any BlueSpice page that accepts a 'title' URL parameter and inspect how it is handled - check if the value appears in the rendered HTML without encoding (view page source)Affected if The title parameter value is reflected unsanitized in the HTML output (raw, unescaped)
-
Test for reflected XSS in title parameterTemporarily inject a benign test payload in the title parameter (e.g., ?title=<script>alert('test')</script>) and observe if the script executes or appears literally in the page sourceAffected if The injected HTML/JavaScript renders as-is without encoding or gets executed in the browser context
You are affected if BlueSpice version is below 4.1.3 AND the commonuserinterface component with the vulnerable title parameter is accessible and reflects unsanitized input in the page.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped4.1.3
Implement proper input validation and output encoding on the title parameter to sanitize user-supplied input before rendering it in HTML context.
Bluespice 4.1.3 or later
- 1. Backup your current BlueSpice installation and database
- 2. Download BlueSpice version 4.1.3 or later from the official source (en.wiki.bluespice.com)
- 3. Install the upgrade following the standard BlueSpice upgrade procedure
- 4. Verify the installation is successful and test that the XSS vulnerability is remediated
