       suexec - Switch user before executing external programs

-V     If you are root, this option displays the compile options of  suexec.  For  security  reasons  all
              configuration options are changeable only at compile time.

Apache HTTP Server                                 2018-07-06                                          SUEXEC(8)

suexec  is  used  by  the  Apache HTTP Server to switch to another user before executing CGI programs. In
       order to achieve this, it must run as root. Since the HTTP daemon  normally  doesn't  run  as  root,  the
       suexec executable needs the setuid bit set and must be owned by root. It should never be writable for any
       other person than root.

       For  further  information  about the concepts and the security model of suexec please refer to the suexec
       documentation (http://httpd.apache.org/docs/2.4/suexec.html).
