Impact

The vulnerability resides in the preview.php file of SourceCodester Class and Exam Timetabling System 1.0, where the course_year_section argument is not properly validated. This introduces a SQL injection flaw (CWE‑74 and CWE‑89). An attacker who can reach this page remotely can inject arbitrary SQL statements, allowing unauthorized reading, modification or deletion of database contents and potentially escalating privileges within the application.

Affected Systems

Risk and Exploitability

The CVSS score of 6.9 indicates moderate severity.
