Some wu-ftpd installations contain a flaw that may allow a malicious user with a user account on the FTP server to execute arbitrary commands as root. The issue is caused by a wu-ftpd misconfiguration in pathnames.h that sets the search path for logged in users to /bin rather then ~/bin. It is possible that the flaw may allow arbitrary command execution resulting in a loss of integrity.
