I had to do this the other day and couldn't find a straightforward way.  I ended up writing the following. Be sure to substitute your own root path and the desired owner, group and permissions.

xquery version "3.1";

import module namespace dbutil="http://exist-db.org/xquery/dbutil";
import module namespace console="http://exist-db.org/xquery/console";

declare function local:setperm($path as xs:string) {
    let $x := sm:chown($path, 'owner')
    let $x := sm:chgrp($path, 'group')
    let $x := sm:chmod($path, 'rwxrwxr--')
    let $x := console:log('Ownership and permissions set on ' || $path)
    return $x
};

let $root := '/db/apps/somepath'
return dbutil:scan(xs:anyURI($root), function($col, $path) {
    let $x := local:setperm(($path, $col)[1])
    return $x
})
