The manipulation of the argument Username leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public 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

A SQL injection vulnerability exists in the Simple Online Hotel Reservation System 1.0 admin login page (/admin/index.php). The 'Username' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL commands. This authentication bypass vulnerability carries a CVSS 9.8 critical rating due to the public exploit availability and remote attack vector.

MitigationReplace dynamic SQL queries with parameterized queries or prepared statements in the affected login functionality. Additionally, implement strict input validation on all user-supplied fields and consider deploying a WAF as a defense-in-depth measure.

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 Simple Online Hotel Reservation System is deployed
    Locate the application's web root directory and confirm the presence of hotel reservation system files, or access the application's login page via web browser
    Affected if The application is present in the environment
  2. Check the installed version
    Inspect application files for version information, typically in a README, version.php, or similar file in the web root, or check the admin panel for version display
    Affected if Version is 1.0 (the only affected version)
  3. Verify admin login page accessibility
    Navigate to /admin/index.php in a web browser or use curl to confirm the page is accessible and returns the login form
    Affected if The admin login page is reachable without authentication
  4. Confirm vulnerable Username parameter exists
    Inspect the HTML form at /admin/index.php or review the source code to verify the login form contains a Username input field that gets processed by the backend
    Affected if The login form accepts a Username parameter and submits to a PHP endpoint without visible sanitization in the client-side code

If the Simple Online Hotel Reservation System version 1.0 is deployed and its /admin/index.php login page is accessible, the Username parameter is vulnerable to SQL injection and the environment is affected.
