Submit #846712: Assessment Management System login.php SQL Injection Vulnerabili v1.0 SQL Injection

# Assessment Management System login.php SQL Injection Vulnerability

A SQL injection vulnerability exists in the login.php file of the Assessment Management System. The application
directly concatenates user-controlled input from the userid and password parameters into an SQL query without proper
sanitization or parameterized statements. As a result, an attacker can inject arbitrary SQL syntax into the
authentication query.

##

## Impact of the Vulnerability

This vulnerability may allow an attacker to manipulate backend SQL queries, bypass authentication, extract database
content, and trigger database error-based responses. In some cases, it may lead to disclosure of sensitive information
such as usernames, password data, or other application records stored in the database.
