## NAME
       suexec - Switch user before executing external programs


## SYNOPSIS
       **suexec **-**V**



## SUMMARY
       **suexec  **is used by the Apache HTTP Server to switch to another user before executing CGI pro‐
       grams. 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>).
