CVE-2025-4037Public exploit

Balance manipulation via unchecked negative transaction amounts

Published Apr 28, 2025 · Updated Apr 28, 2025

Improper input validation in Code Projects ATM Banking 1.0 allows local users to alter account balances through negative transaction amounts. moneyDeposit and moneyWithdraw accept signed negative values without rejecting nonpositive amounts, so deposits subtract funds and withdrawals add funds. Access to the interactive application is required, and exploitation changes only the simulator's calculated balance state.
