Technical details
A SQL injection vulnerability exists in SourceCodester Pharmacy Sales and Inventory System 1.0 within the '/ajax.php?action=save_product' endpoint. The root cause is the improper neutralization of the 'id' parameter before it is used in a SQL query. An unauthenticated remote attacker can exploit this by sending a specially crafted POST request containing malicious SQL commands. Successful exploitation allows for unauthorized database access, data exfiltration, and potential system compromise. A public proof-of-concept (PoC) using boolean-based blind SQL injection has been disclosed.
