CVE-2025-4889Public exploit

Local application crash via unbounded registration input

Published May 18, 2025 · Updated May 19, 2025

Buffer overflow in code-projects Tourism Management System 1.0 allows local users to crash the application through registration input. The AddUser function passes username and password text to scanf conversions without field-width limits, allowing writes past fixed-size fields. Low-privilege local access to the interactive sign-up flow is required; the published proof of concept demonstrates an access-violation crash.
