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 itsourcecode Online Hotel Management System 1.0. Affected is an unknown function of the file /admin/mod_amenities/controller.php?action=add. Executing a manipulation of the argument image can lead to unrestricted upload. It is possible to launch the attack remotely. 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 · moderate confidence

The itsourcecode Online Hotel Management System 1.0 contains an unrestricted file upload vulnerability in /admin/mod_amenities/controller.php?action=add. The 'image' parameter accepts arbitrary file uploads without proper validation, allowing remote attackers to upload malicious PHP scripts and achieve remote code execution.

MitigationImplement strict allowlist-based file validation for both MIME type and extension, store uploads outside the web root, rename uploaded files to prevent execution, and enforce proper authentication/authorization checks on the admin endpoint.

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 itsourcecode Online Hotel Management System is installed
    Search the web root for characteristic files such as 'index.php', 'admin/index.php', or directories named 'mod_amenities', 'hotel', or 'online_hotel_management'. Check page titles, footers, or meta tags for 'itsourcecode' or 'Online Hotel Management System' branding.
    Affected if The application is found in the web directory or responds to HTTP requests.
  2. Determine the installed version
    Review any version files, README files, or meta information in the application root. Check footer content or admin dashboard for version numbers. Compare against version 1.0.
    Affected if The installed version is 1.0 or cannot be determined (treat as potentially affected).
  3. Verify the vulnerable admin endpoint exists
    Attempt to access or enumerate /admin/mod_amenities/controller.php via HTTP requests or directory listing. Check if the path /admin/mod_amenities/ exists in the web root.
    Affected if The directory path /admin/mod_amenities/ exists and contains controller.php.
  4. Check if the admin interface is accessible without proper authentication
    Inspect the application's authentication mechanism for /admin/ endpoints. Determine if authentication is enforced or if the addAmenities function (action=add) can be reached without valid admin credentials.
    Affected if The admin endpoint is accessible without authentication or uses weak/blank credentials.
  5. Inspect upload directories for suspicious files
    Search web-accessible directories (commonly /admin/mod_amenities/, /uploads/, /images/, or /assets/) for unexpected .php, .phtml, or .php5 files. Review file modification timestamps for recent uploads.
    Affected if Executable PHP files exist in upload directories outside of expected template/assets locations.

If the itsourcecode Online Hotel Management System 1.0 is installed and the /admin/mod_amenities/ endpoint is accessible, the environment is likely affected by this unrestricted file upload vulnerability.
