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
A flaw has been found in projectworlds House Rental and Property Listing 1.0. Impacted is an unknown function of the file /app/register.php?action=reg of the component Signup. This manipulation of the argument image causes unrestricted upload. Remote exploitation of the attack is possible. The exploit has been published and may be used.

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 House Rental and Property Listing 1.0 application has an unrestricted file upload vulnerability in the signup functionality at /app/register.php?action=reg. The 'image' parameter accepts files without proper validation, allowing attackers to upload malicious files (e.g., PHP web shells) and achieve remote code execution.

MitigationImplement strict file type validation using both extension allowlists and MIME type checking, validate actual file content/headers, store uploads outside the web root, and disable script execution in upload directories.

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. Locate the application installation
    Search for the presence of register.php in the /app/ directory or any web-accessible directory. Common paths: /app/register.php, /register.php, or within a house-rental/ directory.
    Affected if The file /app/register.php exists on the server.
  2. Verify the application version
    Check for version indicators in source files, such as comments in PHP files, version.txt, README files, or any configuration files that may contain the version number. Compare against version 1.0.
    Affected if The installed version is Projectworlds House Rental And Property Listing 1.0.
  3. Confirm the vulnerable endpoint exists
    Access or inspect the file /app/register.php and verify the 'action=reg' parameter handling exists. Look for the 'image' parameter in form submissions.
    Affected if The register.php file contains an 'image' file upload field and processes it without apparent validation.
  4. Inspect file upload validation logic
    Examine the register.php code for file validation functions. Look for checks on file extension, MIME type, content type, or file content headers before moving the uploaded file.
    Affected if The code lacks or has weak validation - no extension allowlist, no MIME type verification, or no content-type checking before file move operations.
  5. Check upload directory configuration
    Identify where uploaded files are stored. Look for move_uploaded_file() calls or similar file handling functions in register.php. Determine if uploads are stored inside the web root.
    Affected if Uploaded files are saved within the web-accessible directory without disabling script execution.

You are affected if the House Rental And Property Listing 1.0 is installed, the /app/register.php endpoint with the 'image' parameter exists, and there is no proper file type validation or secure upload storage configuration.
