| 제목 | ATM Simulator Improper Input Validation in Financial Transactions v1 Improper Input Validation |
|---|
| 설명 | The ATM Simulator fails to validate transaction amounts, allowing **negative values** in deposits and withdrawals. An attacker can exploit this to:
- **Deposit negative values** → Illegally reduce balance (acts as withdrawal).
- **Withdraw negative values** → Illegally inflate balance (acts as deposit).
- **Bypass financial logic**, leading to incorrect balance calculations.
