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 Reflected XSS. This issue affects CyberMath: from v.1.4 before v.1.5.

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 · moderate confidence

Reflected XSS vulnerability in CyberMath v1.4 allows attackers to inject malicious scripts via user-supplied input that gets reflected in web pages without proper sanitization. The vulnerability stems from improper neutralization of input during page generation.

MitigationUpgrade to CyberMath v1.5 or later. Additionally, implement output encoding and input validation on all user-supplied parameters before rendering.

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 is installed
    Identify if the CyberMath application is running in your environment by checking for web services, installed packages, or application directories related to Nationalkeep Cybermath
    Affected if CyberMath is present in the environment
  2. Check the installed version
    Determine the version of CyberMath by inspecting the application banner, version file, or using the application's /about/version endpoint if available
    Affected if The version is exactly 1.4 (version 1.4 is the only affected version)
  3. Identify accessible web endpoints
    Review the application's exposed HTTP endpoints, particularly any that accept user-supplied input via query parameters, form fields, or URL paths
    Affected if The application exposes web interfaces that accept user input
  4. Test for reflected XSS vulnerability
    Submit a benign test payload (such as a non-executable string like <script>alert('test')</script> or a safe alternative) to suspected input fields and verify if the payload is reflected back in the response without encoding or sanitization
    Affected if User input is reflected in the response without proper output encoding or sanitization (the application does not neutralize special characters)
  5. Verify lack of input validation
    Inspect application logs or intercept HTTP responses to confirm that special characters in user input are passed through unchanged to the HTML output
    Affected if The application reflects unvalidated user input directly into web page content

Your environment is affected if CyberMath version 1.4 is installed and exposes web interfaces that reflect user-supplied input without proper sanitization or output encoding.

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

Upgrade to CyberMath v1.5 or later. Additionally, implement output encoding and input validation on all user-supplied parameters before rendering.

Recommended fix High confidence

CyberMath v.1.5

  1. 1. Identify current CyberMath installation version to confirm affected version (1.4)
  2. 2. Create a complete backup of the CyberMath installation including database and configuration files
  3. 3. Download CyberMath version 1.5 from the official vendor source
  4. 4. Install version 1.5 following the vendor's upgrade instructions
  5. 5. Verify the upgrade was successful by checking the new version number
  6. 6. Test that the reflected XSS vulnerability (CVE-2023-6673) is no longer present by verifying input fields properly sanitize special characters
