CVE-2025-5297Public exploit

Local code execution via unbounded RAM input

Published May 28, 2025 · Updated May 28, 2025

Stack-based buffer overflow in SourceCodester Simple Computer Store System 1.0 allows local users to corrupt memory via RAM input. The Add function in main.c passes attacker-controlled PC.RAM data to gets(), which writes past the 100-byte stack buffer without a length check. Low-privilege local access is required; oversized input can crash the program or overwrite control data for code execution in the program's context.
