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
Unrestricted Upload of File with Dangerous Type vulnerability in 7oroof Medcity medcity allows Upload a Web Shell to a Web Server.This issue affects Medcity: from n/a through < 1.1.9.

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

The Medcity theme contains an unrestricted file upload vulnerability that allows attackers to upload malicious files (web shells) directly to the web server. This vulnerability has a CVSS 10 rating due to the potential for complete system compromise through remote code execution once the web shell is uploaded and accessed.

MitigationRestrict file uploads to safe file types (images, documents) with server-side validation, store uploads outside the web root, disable script execution in upload directories, and upgrade to version 1.1.9 or later.

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 if Medcity theme is installed
    Locate the Medcity theme directory in the web application (typically in wp-content/themes/medcity or similar path) and confirm its presence on the server file system.
    Affected if The Medcity theme directory exists in the themes folder.
  2. Determine the installed Medcity theme version
    Open the theme style.css file or theme.json file within the Medcity theme directory and read the Version: header value.
    Affected if The version is lower than 1.1.9 (e.g., 1.1.8, 1.1.0, or any version prior to the fix).
  3. Locate file upload functionality
    Search the theme files (PHP templates, functions.php, or any upload-handling scripts) for file upload forms or $_FILES handling code.
    Affected if File upload handling code exists within the theme and accepts user-submitted files.
  4. Verify file type validation is present
    Examine the upload handling code to see if server-side validation checks the file extension or MIME type before saving the file.
    Affected if No server-side file type validation is performed, or validation can be bypassed, allowing script files (PHP, JSP, etc.) to be uploaded.
  5. Check upload directory web accessibility
    Identify where uploaded files are stored and determine if that directory is accessible via the web server (within the web root).
    Affected if Uploaded files are stored in a web-accessible directory and script execution is not disabled in that location.

A user is affected if the Medcity theme is installed with a version lower than 1.1.9 and contains file upload functionality that lacks proper server-side validation or stores files in a web-accessible location.
