Memory corruption via crafted CONF command

Published Apr 7, 2025 · Updated Apr 8, 2025

Buffer overflow in PCMan FTP Server 2.0.7 allows remote attackers to corrupt memory via a crafted CONF command. The public record identifies the CONF Command Handler, but neither the record nor its references discloses the buffer, copy operation, or input-length boundary. No authentication or user interaction is required; published evidence establishes memory corruption but does not demonstrate code execution.
