## Technical details

A SQL injection vulnerability exists in Sourcecodester Basic Library System v1.0 within the 'admin_id' parameter of the /librarysystem/load_admin.php component. The application fails to properly sanitize user-supplied input before using it in a SQL query, allowing for Union-based SQL injection. An attacker with high-level administrative privileges can exploit this via a specially crafted GET request to extract sensitive information from the database, such as the database name or other table data. The vulnerability was demonstrated using a payload that leverages a UNION SELECT statement to leak database metadata.
