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
A flaw has been found in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. This impacts an unknown function of the file /postquerypublic.php of the component Post Query Details Page. This manipulation of the argument gnamex causes sql injection. The attack is possible to be carried out remotely. The exploit has been published and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The vendor was contacted early about this disclosure but did not respond in any way.

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

SQL injection vulnerability in the gnamex parameter of /postquerypublic.php in CloudClassroom-PHP-Project allows remote attackers to inject malicious SQL queries. The issue stems from unsanitized user input being directly used in database queries.

MitigationImplement parameterized queries/prepared statements for all database operations and add input validation. If the vendor remains unresponsive, consider disabling the affected component or implementing a web application firewall as a compensating control.

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 CloudClassroom PHP Project installation
    Search the web server document root for files containing 'Cloudclassroom' or 'cloudclassroom' in the filename or check for the presence of the project directory.
    Affected if The project files are found on the server.
  2. Verify installed version is 1.0
    Check for a version file (such as version.php, README, or composer.json) in the project root, or inspect any header/meta tags on the application pages that may display the version.
    Affected if The installed version is 1.0.
  3. Locate the vulnerable script
    Check for the existence of /postquerypublic.php in the web-accessible directories of the application.
    Affected if The file postquerypublic.php exists in the web root.
  4. Assess network exposure
    Verify the application is accessible over HTTP/HTTPS and the endpoint /postquerypublic.php can be reached.
    Affected if The application and the vulnerable script are network-accessible.

The environment is affected if Vishalmathur Cloudclassroom Php Project version 1.0 is installed with the postquerypublic.php script accessible over the network.
