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
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in National Keep Cyber Security Services CyberMath allows Stored XSS. This issue affects CyberMath: from v1.4 before v1.5.

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) vulnerability in CyberMath allows attackers to inject malicious JavaScript code through user inputs that are later displayed without proper sanitization to other users viewing the affected pages.

MitigationUpgrade to CyberMath v1.5 or later which contains the fix; alternatively, implement proper input validation and output encoding on all user-supplied data before rendering in web pages.

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. Confirm CyberMath installation
    Locate the CyberMath application in your environment - check web server document roots, application directories, or container images for 'CyberMath' or 'cybermath' folders/files.
    Affected if The application is present and named CyberMath or cybermath.
  2. Identify installed version
    Check for version files or configuration files within the CyberMath installation directory. Common locations include a 'version', 'VERSION', or 'info' file in the root directory, or check package.json if it's a Node.js application.
    Affected if The discovered version is exactly 1.4.
  3. Verify user input functionality exists
    Identify pages or endpoints that accept user-supplied input and display it back to users. These typically include: user profile fields, comment sections, message boards, search fields, or any form that stores and displays data.
    Affected if User input forms that store and display data are accessible without authentication or to authenticated users.
  4. Inspect application security controls
    Review the application's source code or configuration for input validation and output encoding mechanisms. Look for sanitization functions, HTML encoding, or Content Security Policy headers that handle user-supplied data before rendering.
    Affected if No apparent input sanitization or output encoding is implemented for stored user data, or the application lacks security headers.

You are affected if CyberMath version 1.4 is installed and user-supplied input can be submitted and displayed within the application without sanitization.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to CyberMath v1.5 or later which contains the fix; alternatively, implement proper input validation and output encoding on all user-supplied data before rendering in web pages.

Recommended fix Moderate confidence

CyberMath v1.5

  1. Verify current CyberMath installation version
  2. Obtain CyberMath v1.5 from the official vendor or trusted distribution channel
  3. Back up current configuration and data
  4. Install v1.5 following vendor installation documentation
  5. Verify the upgrade was successful and the application functions correctly
