| Title | SourceCodester Class and Exam Timetabling System V1.0 SQL injection |
|---|
| Description | A SQL injection vulnerability was discovered in SourceCodester Class and Exam Timetabling System V1.0.
Affected endpoint:
/admin/modal_add_course1.php
Vulnerable parameter:
course
The vulnerable endpoint reads the user-controlled POST parameter "course" and uses it in a mysqli_query() call without prepared statements or sufficient input validation. An attacker can inject malicious SQL payloads through this parameter and manipulate the backend database query.
Authentication:
According to the public report, no login or authorization is required to exploit this vulnerability.
Validation:
A POST request to /admin/modal_add_course1.php with a quoted "course" payload returned HTTP 200 and SQL error output without sending an authenticated session cookie. sqlmap validation confirmed time-based blind SQL injection using a MySQL SLEEP payload.
POST parameters:
course, year_section, department, go
Impact:
Successful exploitation may allow unauthorized database access, sensitive data disclosure, data tampering, and service disruption.
Suggested fix:
Use prepared statements and parameter binding, validate and filter all user-controlled input, and restrict database account privileges.
