Technical details
A time-based blind SQL injection vulnerability exists in SourceCodester Loan Management System v1.0 within the 'save_loan' action of the ajax.php file. The application fails to adequately sanitize the 'borrower_id' POST parameter before incorporating it into a database query. An authenticated attacker can exploit this by injecting SQL SLEEP() commands to infer database content based on server response delays. This vulnerability allows for unauthorized data exfiltration from the underlying MySQL database. A proof-of-concept using sqlmap has confirmed the vulnerability.
