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 checksWork through these to decide whether this CVE applies to you.
-
Confirm product and versionIdentify if the deployed application is itsourcecode Free Hotel Reservation System version 1.0. Check application files, headers, or version documentation for the exact version number.Affected if The installed version is itsourcecode Free Hotel Reservation System 1.0 and matches the affected release.
-
Locate the affected PHP fileVerify the existence of the file /hotel/admin/mod_reports/index.php in the web root directory. Inspect the file contents to confirm it processes the 'Home' parameter.Affected if The file /hotel/admin/mod_reports/index.php exists and contains code that handles the 'Home' parameter without proper sanitization.
-
Inspect parameter handling in the codeReview the source code of /hotel/admin/mod_reports/index.php and search for the 'Home' parameter usage. Determine if it is directly interpolated into SQL queries without prepared statements or input validation.Affected if The 'Home' parameter is concatenated into SQL queries without parameterized queries or escaping.
-
Check application accessibilityDetermine if the /hotel/admin/ path is accessible over the network and if authentication is required. Attempt to access the mod_reports module.Affected if The admin panel and mod_reports module are accessible without proper authentication or the 'Home' parameter can be submitted via HTTP requests.
A user is affected if they are running itsourcecode Free Hotel Reservation System version 1.0, the file /hotel/admin/mod_reports/index.php exists, and the 'Home' parameter in that file is processed without SQL injection protection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement parameterized queries (prepared statements) for all database operations in the affected file and add proper input validation/sanitization for the Home parameter. Restrict admin panel access to authorized users only as an additional defense layer.
