Memory corruption via unbounded searchstaff input
Published Apr 17, 2025 · Updated Apr 18, 2025
Buffer overflow in SourceCodester Phone Management System in C 1.0 allows local users to corrupt memory through staff-search input. The searchstaff() function reads an unbounded string with scanf into the 15-byte s buffer, so longer input overwrites adjacent memory. Reaching the function requires the admin password and menu navigation; the published demonstration confirms memory corruption but not code execution.
