Detection & IOCsextracted from sources · hover to see the quote

othervsFTPd ([0-9.]+)
  • Banner-based detection: check FTP banner for 'vsFTPd' string and extract version; flag if version is <= 3.0.2
  • Send a 4-byte null hex probe (00000000) on TCP port 21 and inspect the raw response for the vsFTPd banner to identify vulnerable versions
  • The vulnerability is related to improper parsing of the deny_file configuration directive; audit vsftpd.conf for use of deny_file on servers running vsftpd <= 3.0.2
  • ·Red Hat Product Security determined this is NOT a security vulnerability for RHEL 5/6/7, citing the vsftpd.conf man page which warns deny_file should not be used for serious access control and that filesystem permissions should be preferred instead.
  • ·The man page for vsftpd.conf explicitly warns that deny_file is not suitable for serious access control and that care must be taken when files are accessible by multiple names (e.g., via symlinks or hard links).
  • ·Debian fixed the issue in vsftpd package version 3.0.2-18 across bookworm, bullseye, forky, sid, and trixie.
