CVE-2025-1587Public exploit

Local memory corruption via unbounded scanf input

Published Feb 23, 2025 · Updated Apr 2, 2025

Buffer overflow in Add New Record in SourceCodester Telecom Billing Management System 1.0 allows local users to corrupt process memory. The addrecords function in main.cpp passes the fixed-size name buffer to scanf without a field-width limit, so input longer than 50 bytes overwrites adjacent memory. Reachability requires local access, the application login, and menu option one; the demonstrated result is memory corruption, not code execution.
