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.
-
Confirm the SourceCodester CET Automated Grading System installationLocate the application directory and check for version identifiers in source files, README, or configuration. Common paths include /var/www/html or similar web root directories where the PHP application is hosted.Affected if The system is running SourceCodester CET Automated Grading System version 1.0 or another unpatched version of this software.
-
Verify if the Student Self-Registration endpoint is accessibleTest access to the registration functionality by attempting to reach the registration page via /index.php with registration-related parameters or paths. Check web server access logs for registration-related requests.Affected if The self-registration endpoint is publicly accessible without authentication requirements.
-
Inspect access control logic in index.php and related filesExamine the source code of index.php and any included files related to user registration. Look for authentication checks, session validation, or role verification before allowing self-registration actions.Affected if The code lacks proper authentication/authorization checks before permitting self-registration operations.
-
Review user role and permission configurationCheck the database or configuration files to determine how user roles are defined and whether any guest/unauthenticated users can be registered as students without admin approval.Affected if Unauthenticated users can self-register as students without proper role-based access control validation.
The environment is affected if it runs SourceCodester CET Automated Grading System 1.0 with the self-registration endpoint exposed and lacking proper authentication/authorization controls in index.php.

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 dataImplement proper authentication and role-based access control (RBAC) for the registration endpoint, including validation that users have appropriate permissions before allowing self-registration actions.
