CGI script calling sudo

Hi,

I have a CGI script with the following permissions:

    -rwxr-xr-x  root     root
root:object_r:httpd_unconfined_script_exec_t  mpver.cgi

This script is internally invoking "sudo". Sudo itself is a wrapper for

    -rwxr-xr-x  root     root     system_u:object_r:shell_exec_t
/usr/sbin/sesh

This invocation fails, however:

    Jul 17 20:51:35 fibudbserver kernel: audit(1153162295.966:6): avc:
    denied  { transition } for  pid=20441 comm="sudo" name="sesh"
    dev=sda1 ino=235570 scontext=user_u:system_r:httpd_unconfined_script_t
    tcontext=root:system_r:unconfined_t tclass=process

What do I need to change?

Regards,

Jochen
