DHCP server cannot execute script: permission denied exit 32512
I created a DHCP server on ubuntu 18:04 using isc-dhcp-server that normally works. I want to run a script located in /user/sbin but get error of permission denied with exit status 32512. Probably it's a permission error but I'm not expert. This is my dhcp server located in:

/etc/dhcp/dhcpd.conf

Code:
default-lease-time 86400;
max-lease-time 7200;

ignore client-updates;
authoritative;

use-host-decl-names on;
log-facility local7;


subnet 192.168.1.0 netmask 255.255.255.0 {
    range 192.168.1.101 192.168.1.150;
    option subnet-mask 255.255.255.0;
    option routers 192.168.1.3;
    option domain-name-servers 192.168.1.100;
    ddns-rev-domainname "in-addr.arpa.";
}

on commit {
    set ClientIP = binary-to-ascii(10, 8, ".", leased-address);
    set ClientMac = binary-to-ascii(16, 8, ":", substring(hardware, 1, 6));
    log(concat("Commit: IP: ", ClientIP, " Mac: ", ClientMac));
    execute("/usr/sbin/update_DB.sh", "commit", ClientIP, ClientMac);
}

/var/log/syslog

Code:
Apr  8 14:28:05 dhcp dhcpd[1223]: Commit: IP: 192.168.1.102 Mac: XXX
Apr  8 14:28:05 dhcp dhcpd[1223]: execute_statement argv[0] = /usr/sbin/update_DB.sh
Apr  8 14:28:05 dhcp dhcpd[1223]: execute_statement argv[1] = commit
Apr  8 14:28:05 dhcp dhcpd[1223]: execute_statement argv[2] = 192.168.1.102
Apr  8 14:28:05 dhcp dhcpd[1223]: execute_statement argv[3] = XXX
Apr  8 14:28:05 dhcp dhcpd[1227]: Unable to execute /usr/sbin/update_DB.sh: Permission denied
Apr  8 14:28:05 dhcp dhcpd[1223]: execute: /usr/sbin/update_DB.sh exit status 32512

anyone knows how to solve it, please? Thanks!

NAME

       dhcp - Dynamic Host Configuration Protocol

DESCRIPTION

       Dynamic	Host Configuration Protocol (DHCP) enables host systems in a TCP/IP network to be configured automatically for the network as they
       boot. DHCP uses a client/server mechanism: servers store configuration information  for	clients,  and  provide	that  information  upon  a
       client's request. The information can include the client's IP address and information about network services available to the client.

       This manual page provides a brief summary of the Solaris DHCP implementation.

   Solaris DHCP Client
       The  Solaris  DHCP  client  is implemented as background daemon, dhcpagent(1M). This daemon is started automatically during bootup if there
       exists at least one dhcp.interface file in /etc. Only interfaces with a corresponding /etc/dhcp.interface file are automatically configured
       during  boot.  Network  parameters  needed for system configuration during bootup are extracted from the information recieved by the daemon
       through the use of the dhcpinfo(1) command. The daemon's default behavior can be altered by changing the tunables in the  /etc/default/dhc-
       pagent  file.  The  daemon is controlled by the ifconfig(1M) utility. Check the status of the daemon using the netstat(1M) and ifconfig(1M)
       commands.

   Solaris DHCP Server
       The Solaris DHCP server is implemented as a background daemon, in.dhcpd(1M). This daemon can deliver network configuration  information	to
       either  BOOTP  or  DHCP	clients.  The Solaris DHCP service can be managed using the dhcpmgr(1M) GUI or the command line utilities dhcpcon-
       fig(1M), dhtadm(1M), and pntadm(1M).

   DHCP Configuration Tables
       The Solaris DHCP server stores client configuration information in the following two types of tables:

       dhcptab tables	       Contain macros and options (also known as symbols), used to construct a package	of  configuration  information	to
			       send to each DHCP client. There exists only one dhcptab for the DHCP service. The dhcptab(4) can be viewed and mod-
			       ified using the dhtadm(1M) command or dhcpmgr(1M) graphical utility. See dhcptab(4) for more information about  the
			       syntax of dhcptab records. See dhcp_inittab(4) for more information about the DHCP options and symbols.

       DHCP network tables     DHCP  network  tables,  which  contain  mappings of client IDs to IP addresses and parameters associated with those
			       addresses. Network tables are named with the IP address of the network, and can be created,  viewed,  and  modified
			       using  the  pntadm  command  or	dhcpmgr  graphical utility. See dhcp_network(4) for more information about network
			       tables.
