Description

A Blind SQL Injection vulnerability exists in SourceCodester Loan Management System v1.0. The vulnerability is located in the ajax.php file (specifically the save_loan action). The application fails to properly sanitize user input supplied to the "borrower_id" parameter in a POST request, allowing an authenticated attacker to inject malicious SQL commands.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
