NVD · unedited
Unrestricted Upload of File with Dangerous Type vulnerability in mojoomla WPAMS apartment-management allows Upload a Web Shell to a Web Server.This issue affects WPAMS: from n/a through <= 44.0 (17-08-2023).

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 WPAMS apartment-management WordPress plugin contains an unrestricted file upload vulnerability that allows authenticated attackers to upload malicious PHP files (web shells) to the web server. This enables remote code execution and complete server compromise.

MitigationUpdate to a patched version of WPAMS if available, or implement strict server-side file type validation with allowlist, store uploads outside the webroot, disable script execution in upload directories, and consider WAF deployment as interim protection.

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 WPAMS plugin is installed
    Check the WordPress plugins directory for a folder named 'wpams', 'wp-ams', 'apartment-management', or similar variants. Look in wp-content/plugins/ for any plugin with 'wpams' or 'apartment' in the folder name.
    Affected if The WPAMS apartment-management plugin is present in the plugins directory
  2. Determine the installed WPAMS version
    Open the main plugin PHP file (typically plugin-name.php in the WPAMS folder) and look for the version header comment, or check the plugin's main class/header for a version constant. Compare the found version against any published version information for the plugin.
    Affected if A version of WPAMS is installed and can be identified
  3. Locate the file upload functionality
    Search the plugin directory for PHP files containing 'upload', 'file', or 'move_uploaded_file' functions. Look for form handlers or AJAX endpoints that process file uploads. Common paths include /wp-content/plugins/[wpams-folder]/includes/ or /controllers/.
    Affected if File upload handling code exists within the WPAMS plugin
  4. Verify if upload endpoint requires authentication
    Examine the upload handling code to determine if it checks user authentication (is_user_logged_in(), current_user_can()) or authorization before processing uploads. Look at the beginning of upload handler functions.
    Affected if The upload functionality processes requests without verifying user login status or permissions
  5. Inspect file type validation logic
    In the upload handler code, look for $_FILES processing and any type checking (mime_content_type, getimagesize, finfo_file). Determine if the code relies solely on file extension checking or client-provided MIME types without server-side validation.
    Affected if The upload code does not perform server-side validation of file types (magic bytes/content inspection) and accepts any file extension

A user is affected if the WPAMS apartment-management plugin is installed and its upload functionality allows unauthenticated or poorly validated file uploads.
