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

A SQL injection vulnerability exists in the Simple Online Hotel Reservation System 1.0 in the room_id parameter of /add_query_reserve.php. Remote attackers can inject malicious SQL queries due to unsanitized user input being used directly in database operations.

MitigationReplace direct string concatenation in SQL queries with prepared statements/parameterized queries. Additionally, implement input validation on the room_id parameter and apply output encoding. Check vendor for official patches.

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 the application version
    Locate and inspect the application's version identifier (typically in an about page, footer, or version file). Compare it to version 1.0.
    Affected if The application is Simple Online Hotel Reservation System version 1.0
  2. Verify the affected script exists
    Check for the presence of /add_query_reserve.php in the web root directory of the application.
    Affected if The file add_query_reserve.php exists in the web-accessible directory
  3. Inspect the room_id parameter handling
    Review the source code of add_query_reserve.php and locate the code handling the room_id parameter. Check if this parameter is used directly in SQL queries without sanitization or prepared statements.
    Affected if The room_id parameter is used in SQL queries without parameterized queries, input validation, or sanitization functions
  4. Confirm database interaction exists
    Verify that the application connects to a database and that the affected script performs database operations using the room_id parameter.
    Affected if The script executes database queries using the room_id parameter from user input without protection

A user is affected if they are running Simple Online Hotel Reservation System version 1.0 with the add_query_reserve.php script accessible and the room_id parameter handled in SQL queries without prepared statements or input sanitization.
