Kerentanan Client-Side Enforcement of Server-Side Security pada oretnom23 loan management system. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

A Business Logic vulnerability exists in SourceCodester Loan Management System v1.0 due to improper server-side validation. The application allows administrators to create "Loan Plans" with specific interest rates. While the frontend interface prevents users from entering negative numbers, this constraint is not enforced on the backend. An authenticated attacker can bypass the client-side restriction by manipulating the HTTP POST request to submit a negative value for the interest_percentage. This results in the creation of loan plans with negative interest rates.
