| Title | sourcecodester Class and Exam Timetabling System V1.0 SQL injection |
|---|
| Description | During the security review of "Class and Exam Timetabling System",I discovered a critical SQL injection vulnerability in the "/preview6.php" file. This vulnerability stems from insufficient user input validation of the 'course_year_section‘ parameter, allowing attackers to inject malicious SQL queries. Therefore, attackers can gain unauthorized access to databases, modify or delete data, and access sensitive information. Immediate remedial measures are needed to ensure system security and protect data integrity. |
