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
Direct static code injection vulnerability in editcss.php in Gravity Board X (GBX) 1.1 allows remote attackers to execute arbitrary PHP code, HTML, and script via the csscontent parameter, which is directly inserted into the gbxfinal.css file.

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

A direct static code injection vulnerability exists in editcss.php of Gravity Board X 1.1 where the csscontent parameter is written directly to the gbxfinal.css file without any sanitization or validation, allowing attackers to inject arbitrary PHP code, HTML, or JavaScript that will be executed when the CSS file is served.

MitigationImplement strict input validation and sanitization on the csscontent parameter before writing to CSS files, or disable the editcss.php functionality entirely if not required.

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 Gravity Board X installation version
    Locate the version file or index page of the installation and verify the installed version is 1.1. Check files like version.php, index.php, or a readme file for the version number.
    Affected if The installed version is Gravity Board X 1.1 exactly.
  2. Verify editcss.php file exists
    Search the web root directory for the file editcss.php. Common paths may include /editcss.php, /admin/editcss.php, or /forum/editcss.php depending on installation location.
    Affected if The editcss.php file exists in the web-accessible directory.
  3. Check write permissions on gbxfinal.css
    Locate the gbxfinal.css file (typically in the same directory as editcss.php or in a /css/ folder) and verify if the web server process has write permissions to this file.
    Affected if The gbxfinal.css file exists and is writable by the web server user.
  4. Inspect gbxfinal.css for injected code
    Open gbxfinal.css in a text editor or download it via HTTP and examine the contents for any unexpected PHP code blocks (<?php ... ?>), suspicious JavaScript, or base64-encoded strings that do not resemble normal CSS.
    Affected if The file contains PHP code, suspicious script tags, or code that was not authored by the administrator.
  5. Check HTTP access to editcss.php
    Attempt to access editcss.php directly via HTTP (e.g., GET request to the full URL) to confirm the script is executable and returns a response.
    Affected if The script is accessible via HTTP and accepts parameters without authentication errors.

A system is affected if it runs Gravity Board X 1.1 with editcss.php present and accessible, and the gbxfinal.css file is writable or already contains injected code.
