    A flaw exists in the mod_ctrls module of ProFTPD, normally used to
    allow FTP server administrators to configure the daemon at runtime.
  
Impact :

    An FTP server administrator permitted to interact with mod_ctrls could
    potentially compromise the ProFTPD process and execute arbitrary code
    with the privileges of the FTP Daemon, which is normally the root user.
  
Workaround :

    Disable mod_ctrls, or ensure only trusted users can access this
