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
Multiple stored cross-site scripting (XSS) vulnerabilities in the submit_add_user.asp endpoint of DDSN Interactive Acora CMS v10.7.1 allow attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the First Name and Last Name parameters.

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

Stored cross-site scripting (XSS) vulnerabilities exist in the submit_add_user.asp endpoint of DDSN Interactive Acora CMS v10.7.1. Attackers can inject malicious scripts into the First Name and Last Name fields when creating new users. Since this is stored XSS, the payload persists in the application and executes whenever other users view the affected user data.

MitigationImplement robust server-side input validation and output encoding for all user-supplied fields in the user creation functionality. Sanitize or reject HTML/script tags at the server level before storing user input, and ensure proper context-aware output encoding when displaying user data.

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 Acora CMS version
    Locate the version information in the application - typically found in the admin dashboard under 'About' or 'System Info', or check version files in the web root directory. Compare the installed version to v10.7.1.
    Affected if The installed version matches 10.7.1 or falls within the affected range around this version.
  2. Verify submit_add_user.asp exists
    Access the submit_add_user.asp endpoint through the web browser or by making an HTTP request to the path (typically /admin/submit_add_user.asp or /submit_add_user.asp). Check if the page loads and presents a user creation form.
    Affected if The endpoint exists and is accessible, indicating the vulnerable component is present.
  3. Confirm user creation is enabled
    Log in to the Acora CMS admin panel and navigate to the user management section. Verify that the functionality to create new users is available and operational.
    Affected if User creation functionality is enabled and accessible to the attacker.
  4. Inspect database for stored XSS payloads
    Query the user database table (typically named users or similar) and examine the first_name and last_name columns for any suspicious patterns such as <script>, javascript:, onerror=, or other HTML/script tags.
    Affected if The database contains user records with malicious script payloads in First Name or Last Name fields.
  5. Review user list in admin panel
    View the list of users in the admin interface. Observe whether any user entries trigger JavaScript execution or display abnormal behavior when rendered in the browser.
    Affected if Users with XSS payloads in name fields are present and render unsafely in the UI.

A user is affected if they are running Acora CMS v10.7.1 (or an affected version), the submit_add_user.asp endpoint exists and is accessible, and malicious scripts are found stored in the First Name or Last Name database fields.
