CVE-2025-4497Public exploit

Local crash via unbounded password input

Published May 10, 2025 · Updated May 12, 2025

Classic buffer overflow in Simple Banking System 1.0 allows local users to crash the application with an overlong sign-in password. The Sign In routine writes getch() results into the 18-byte password2 stack buffer until Enter is pressed, incrementing the index without a bounds check or null termination. Any local user able to launch the program and reach Sign In can overwrite adjacent stack memory; the published proof of concept demonstrates an access-violation crash, not code execution.
