Executive brief
The Sourcecodester Online Reviewer System, a web application for managing and conducting exams, contains a security flaw in its administrative interface. An attacker with administrative privileges can exploit this vulnerability to gain unauthorized access to the underlying database. This could lead to the exposure of sensitive information, such as exam questions, student data, or system configurations.
Technical details
A SQL injection vulnerability exists in Sourcecodester Online Reviewer System v1.0 within the '/system/system/admins/assessments/examproper/exam-update.php' file. The application fails to properly sanitize the 'test_id' GET parameter before using it in a database query. An authenticated attacker with high privileges (administrator) can exploit this by submitting a crafted URL containing a UNION-based SQL payload. This allows the attacker to extract sensitive information from the database, such as the database name or other table data. The vulnerability is confirmed in environments running PHP 8.1.
