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 SQL Injection vulnerability exists in the takeassessment2.php endpoint of the CloudClassroom-PHP-Project 1.0, where the Q5 POST parameter is directly embedded in SQL statements without sanitization.

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 takeassessment2.php endpoint of CloudClassroom-PHP-Project 1.0 where the Q5 POST parameter is directly concatenated into SQL queries without sanitization or use of parameterized queries, allowing remote attackers to inject malicious SQL code.

MitigationReplace direct SQL string concatenation with prepared statements (parameterized queries) for the Q5 parameter, and implement input validation 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 CloudClassroom installation
    Locate the CloudClassroom application and determine its version by checking project files, composer.json, or any version metadata in the web root directory
    Affected if The installed version is CloudClassroom-PHP-Project version 1.0
  2. Locate vulnerable endpoint file
    Search the web root for the file takeassessment2.php and confirm its existence
    Affected if The file takeassessment2.php exists in the application directory
  3. Verify Q5 parameter handling in SQL queries
    Open takeassessment2.php and search for SQL query construction involving the Q5 POST parameter. Look for patterns like $Q5 or $_POST['Q5'] directly concatenated into query strings without prepare() or parameterized binding
    Affected if The Q5 POST parameter is concatenated directly into SQL queries without using prepared statements or parameter binding
  4. Confirm endpoint is accessible
    Check that the takeassessment2.php endpoint is accessible via HTTP POST requests and processes the Q5 parameter
    Affected if The endpoint accepts Q5 as a POST parameter and processes it in database queries without sanitization

A system is affected if it runs CloudClassroom-PHP-Project version 1.0 with the takeassessment2.php endpoint that handles the Q5 POST parameter via direct SQL string concatenation rather than prepared statements

Mitigation

Replace direct SQL string concatenation with prepared statements (parameterized queries) for the Q5 parameter, and implement input validation as a defense-in-depth measure.
