Daemon crash via oversized RNTO command

Published Jan 25, 2024 · Updated May 30, 2025

Denial of service in Ezhometech EzServer 6.4.017 allows remote attackers to crash the FTP daemon with an oversized RNTO command. The FTP command handler processes an oversized RNTO string without correctly limiting the data volume, causing the server process to terminate. Network reachability is sufficient; no credentials or user interaction are required, and successful exploitation interrupts FTP service for legitimate users.
