CVE-2025-4498Public exploit

Local application crash via unchecked bus-number input

Published May 10, 2025 · Updated May 12, 2025

Stack-based buffer overflow in Install Bus in Code Projects Simple Bus Reservation System 1.0 allows local users to crash the app via overlong input. The a::install method reads bus-number text into bus[p].busn without a length limit and increments p without enforcing the 10-element bus array bound. Local interactive access is required; the public proof of concept demonstrates an EXCEPTION_ACCESS_VIOLATION crash, and the application has no login gate.
