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
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Mava Software Hotel Management System allows SQL Injection. This issue affects Hotel Management System: before 2.0.

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

SQL Injection vulnerability in Mava Software Hotel Management System allows attackers to inject malicious SQL queries through unsanitized user inputs. The critical CVSS 9.8 score indicates this is easily exploitable and could lead to complete database compromise, including unauthorized access to sensitive guest data, credentials, and potential system takeover.

MitigationUpgrade to version 2.0 or later, which should contain patched code. If upgrading is not immediately possible, implement input validation and parameterized queries (prepared statements) for all database interactions to block SQL injection vectors.

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. Confirm Mava Hotel Management System is installed
    Search for Mava Hotel Management System files on the server, typically found in web root directories (e.g., /var/www/, /htdocs/, C:\inetpub\wwwroot\) or check for a service/process named 'mava' or 'hotel-management'.
    Affected if The software is present on the system.
  2. Identify installed version
    Look for a version file, about page, or configuration file within the Mava installation directory. Common locations include version.txt, config.php, or the main index.php header comments. Compare the version number to the affected range.
    Affected if The installed version is below 2.0 (e.g., 1.x, 1.9.x, etc.).
  3. Verify web interface is accessible
    Attempt to access the application's login or registration pages via HTTP/HTTPS to confirm the web-facing component is active.
    Affected if The web interface is publicly or internally accessible.
  4. Identify user input fields
    Examine the application for forms, search fields, login inputs, booking fields, or URL parameters that accept user-supplied data and interact with the database.
    Affected if User input fields exist that are not using parameterized queries (prepared statements).

If Mava Hotel Management System is installed and the version is below 2.0 with an accessible web interface containing user input fields, the environment is likely affected by this SQL injection vulnerability.

Upgrade available Upgrade to 2.0 or later
Fixed in 2.0
Interim mitigation

Upgrade to version 2.0 or later, which should contain patched code. If upgrading is not immediately possible, implement input validation and parameterized queries (prepared statements) for all database interactions to block SQL injection vectors.

Recommended fix Moderate confidence

Version 2.0

  1. 1. Identify all deployed instances of Mava Software Hotel Management System currently in use
  2. 2. Verify the current version number of each instance (typically found in About or System Info section)
  3. 3. If version is below 2.0, plan for upgrade to version 2.0 or later
  4. 4. Before upgrading, perform a full backup of the database and application files
  5. 5. Review upgrade documentation provided by Mava Software
  6. 6. Execute upgrade to version 2.0 in a test environment first
  7. 7. Validate all functionality works correctly after upgrade
  8. 8. Deploy the upgraded version to production
