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.
-
Locate the Simple Online Hotel Reservation System installationSearch for the presence of the application on the server by identifying directories containing files typical to this system (e.g., index.php, booking files, admin folder) or check web root for hotel reservation related contentAffected if The application directory structure is found on the server
-
Verify the affected file existsCheck for the presence of /admin/checkout_query.php in the web application directoryAffected if The file /admin/checkout_query.php exists in the application installation
-
Confirm the application versionExamine any version files, headers, or metadata within the application to determine if it is version 1.0Affected if The installed version is exactly 1.0 (no other versions are listed as affected)
-
Check admin access controlInspect the /admin/ directory to determine if access controls are properly enforced (authentication required) or if the checkout_query.php file is publicly accessible without authenticationAffected if The /admin/checkout_query.php endpoint is accessible without authentication (no login requirement)
-
Review the vulnerable parameter in source codeExamine the source code of /admin/checkout_query.php and locate the transaction_id parameter usage - check if it is directly concatenated into SQL queries without sanitization or parameterized queriesAffected if The transaction_id parameter is used in SQL queries without prepared statements, parameter binding, or input sanitization
The environment is affected if Simple Online Hotel Reservation System version 1.0 is installed, the /admin/checkout_query.php file exists, and the transaction_id parameter is used in unsanitized SQL queries within that file.

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 the transaction_id parameter and all other user inputs in the affected file to prevent SQL injection attacks.
