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 · unedited
Vulnerability in CMS Made Simple 2.2.14, which does not sufficiently encode user-controlled input, resulting in a Cross-Site Scripting (XSS) vulnerability through /admin/adduser.php, in multiple parameters. This vulnerability could allow a remote attacker to send a specially crafted JavaScript payload to an authenticated user and partially take over their browser session.

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 · high confidence

Cross-Site Scripting (XSS) vulnerability in CMS Made Simple 2.2.14 admin interface at /admin/adduser.php. Multiple parameters in the user creation form do not properly encode user-controlled input, allowing injection of malicious JavaScript that can execute in authenticated users' browsers and partially hijack their sessions.

MitigationApply proper output encoding/escaping for all user-supplied parameters in adduser.php before rendering them in HTML context. Validate input on the server side and implement Content Security Policy headers as defense-in-depth.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify CMS Made Simple installation
    Check for CMS Made Simple by looking for its characteristic directory structure, admin login page, or by searching for known files like /lib/ from the web root.
    Affected if CMS Made Simple is not installed on this system (not applicable).
  2. Determine installed version
    Locate the version file or check the admin footer, typically found in the admin dashboard or in a VERSION file in the installation root directory.
    Affected if The installed version is not 2.2.14 (only version 2.2.14 is affected).
  3. Verify vulnerable file exists
    Check if the file /admin/adduser.php exists in the web root. This is the file containing the XSS vulnerability.
    Affected if The file adduser.php does not exist or the /admin/ interface is not accessible.
  4. Confirm admin access to user creation form
    Log into the CMS Made Simple admin interface and navigate to /admin/adduser.php or access the user creation functionality through the admin panel.
    Affected if You cannot access the admin interface or user creation form; the vulnerability requires an authenticated admin session to exploit.

You are affected only if your installed CMS Made Simple version is exactly 2.2.14 and you have access to the admin interface where the user creation form at /admin/adduser.php can be accessed.

Mitigation
