Filesystem disclosure via pre-authentication directory listing
Published Oct 5, 2023 · Updated Sep 19, 2024
Information disclosure in NetBSD ftpd before 20230930 and tnftpd before 20231001 allows remote attackers to list directory contents. The FTP command parser accepts MLST and MLSD before authentication instead of requiring a logged-in session, then returns metadata for entries in the daemon's current directory. No credentials or user interaction are required, but disclosure is limited to the current ftpd process directory.
