Technical details

A SQL injection vulnerability exists in PHPGurukul Online Shopping Portal Project 2.1 within the '/categorywise-products.php' file. The root cause is the failure of the Parameter Handler component to properly sanitize or validate the 'cid' GET parameter before using it in a database query. A remote attacker with low privileges can exploit this via boolean-based blind, time-based blind, or UNION-based SQL injection techniques. Successful exploitation allows for unauthorized database access, data exfiltration, and potential system compromise. A public exploit (PoC) has been released.
