CVE-2025-50868
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 · uneditedA SQL Injection vulnerability exists in the takeassessment2.php file of CloudClassroom-PHP-Project 1.0. The Q4 POST parameter is not properly sanitized before being used in SQL queries.
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 confidenceA SQL Injection vulnerability exists in the Q4 POST parameter of takeassessment2.php in CloudClassroom-PHP-Project 1.0. User-supplied input is directly incorporated into SQL queries without sanitization or parameterization, allowing an attacker to manipulate query logic.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify CloudClassroom-PHP-Project installationLocate the CloudClassroom-PHP-Project web application in your web server root directory. Check for version.php, README, or composer.json to confirm version 1.0 is deployed.Affected if The application is CloudClassroom-PHP-Project version 1.0
-
Locate takeassessment2.phpSearch the web root for the file takeassessment2.php. In PHP applications, this is typically found in the assessment or quiz handling directory.Affected if The file takeassessment2.php exists in the application
-
Examine Q4 POST parameter handlingOpen takeassessment2.php and search for code that handles the Q4 parameter from $_POST. Look for SQL queries that include $Q4 or $_POST['Q4'] directly in the query string.Affected if The file contains SQL queries that incorporate the Q4 POST parameter without sanitization
-
Verify lack of prepared statementsReview the SQL query code around the Q4 parameter. Check if the query uses prepare() and bindParam()/bindValue() methods, or if it uses direct string concatenation with quotes around the Q4 value.Affected if The Q4 parameter is concatenated directly into the SQL query string without using prepared statements or parameter binding
You are affected if CloudClassroom-PHP-Project 1.0 is installed and takeassessment2.php contains SQL queries that directly incorporate the Q4 POST parameter without prepared statements.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace direct string concatenation in SQL queries with prepared statements or parameterized queries to properly sanitize the Q4 POST parameter before executing database operations.
