CVE-2024-2331Network attack vector

Authenticated memory corruption via unchecked ad_code copy

Published Mar 9, 2024 · Updated Apr 16, 2025

Buffer overflow in System.cpp in SourceCodester Tourist Reservation System 1.0 allows remote authenticated users to corrupt memory via ad_code. The ad_writedata function copies attacker-controlled ad_code data into a bounded destination without first verifying that the input fits. Network access and a valid account are required; public evidence does not establish code execution, a crash, or another specific post-corruption outcome.
