CVE-2025-4038Public exploit

Local crash via unbounded reservation name input

Published Apr 28, 2025 · Updated Apr 28, 2025

Stack-based buffer overflow in Code Projects Train Ticket Reservation System 1.0 allows local users to crash the program via a crafted name. The reservation() function reads a ticket holder's name into the 50-byte passdetails.name stack buffer with gets(), which performs no bounds check. A user must pass the program's login and select ticket reservation; the published proof of concept demonstrates an access-violation crash, not code execution.
