ftpd.c in (1) wu-ftpd 2.4.2 and (2) ftpd in HP HP-UX B.11.11 assigns uid 0 to the FTP client in certain operating-system misconfigurations in which PAM authentication can succeed even though no passwd entry is available for a user, which allows remote attackers to gain privileges, as demonstrated by a login attempt for an LDAP account when nsswitch.conf does not specify LDAP for passwd information.

Security readout for executives and security teams

This old FTP daemon flaw can turn a configuration mistake into root-level access. If PAM accepts a user but the system cannot find a matching passwd record, vulnerable ftpd code may assign uid 0. The business risk is highest for legacy HP-UX or wu-ftpd systems that still expose FTP. Exposure is likely limited to legacy FTP services running wu-ftpd 2.4.2 or HP-UX B.11.11 ftpd, especially where PAM and passwd name-service sources are inconsistent. Modern systems without these FTP daemons are not shown as affected in the supplied sources. Prioritize investigation if legacy FTP is still in use, especially on HP-UX. The flaw can lead to root privileges, but evidence points to a narrow legacy and configuration-dependent exposure rather than broad modern impact. Mitigation focus: Inventory systems running wu-ftpd 2.4.2 or HP-UX B.11.11 ftpd.; Review HP advisory HPSBUX02356 and upstream patch details before changing production systems.; Correct PAM and nsswitch passwd-source alignment for LDAP-backed accounts..
