The Auth API in ProFTPD before 20070417, when multiple simultaneous authentication modules are configured, does not require that the module that checks authentication is the same as the module that retrieves authentication data, which might allow remote attackers to bypass authentication, as demonstrated by use of SQLAuthTypes Plaintext in mod_sql, with data retrieved from /etc/passwd.

Security readout for executives and security teams

This flaw could let an unauthenticated remote user get past ProFTPD login checks in certain mixed authentication setups. It matters most for legacy FTP servers that still run ProFTPD builds before the 20070417 fix and use multiple authentication modules. Exposure appears limited to ProFTPD before 20070417 with multiple simultaneous authentication modules. Public-facing FTP services and legacy Linux packages are the highest-priority inventory targets. The source bundle does not provide precise CPEs or a full affected-version range. Treat as high priority only where legacy ProFTPD is still deployed. The likely blast radius is narrow, but successful authentication bypass on a public FTP server can expose files, credentials, or operational workflows. Mitigation focus: Upgrade ProFTPD to a vendor package containing the 20070417 Auth API fix.; Check Debian, Red Hat, Mandriva, or distribution-specific advisories for supported fixed packages.; Avoid mixed simultaneous authentication-module configurations until vendor guidance is confirmed..
