| عنوان | SourceCodester Loan Management System 1.0 Business Logic Errors |
|---|
| الوصف | A business logic vulnerability exists in Loan Management System 1.0. The issue is located in the save_plan action of the file ajax.php. The application lacks server-side validation for the 'penalty_rate' POST parameter. An authenticated attacker can bypass client-side restrictions to submit negative values, resulting in the creation of loan plans with negative penalty rates and corrupting overdue payment calculations. |
