## Technical details

A SQL injection vulnerability exists in itsourcecode Construction Management System V1.0 within the 'emp_id' parameter of the /borrowedequip.php component. The application fails to properly sanitize or validate user-supplied input before incorporating it into SQL queries. A remote attacker with low-level authenticated access can exploit this by sending specially crafted GET requests, potentially using time-based blind injection techniques (e.g., using SLEEP functions). Successful exploitation allows for unauthorized database access, data leakage, and potential system control. A proof-of-concept exploit using sqlmap has been publicly disclosed.
