Symptoms
-
The directive disable_functions cannot be changed using the article How to disable PHP functions globally?
-
After changing the directive disable_functions in Plesk in Domains > example.com > PHP Settings, domain's phpinfo still shows the old value.
-
The configuration file
/var/www/vhosts/system/example.com/etc/php.inicontains the default value:# grep "disable_functions" /var/www/vhosts/system/example.com/etc/php.ini
disable_functions = "opcache_get_status"
Cause
This is Plesk bug PPPM-9216, which is planned to be fixed in one of the future product updates.

-
Go to Extensions > My Extensions > Panel.ini Editor > Open > Editor.
-
Put the desired values for the parameter
disable_functionsas follows and click Save:CONFIG_TEXT: [php]
settings.performance.disable_functions.values[]=base64_decode
settings.performance.disable_functions.default=base64_decode -
Go to Service Plans > plan_name > PHP Settings.
-
Check that the parameter
disable_functionshas the correct value. -
Click Update & Sync.
Warning: So the value of the parameter
disable_functionsis propagated to the domain's PHP Settings, the Hosting performance settings management permission must be disabled in Service Plans > plan_name > Permissions. -
Repeat the steps 5-7 for each service plan.

OK folks, we need this bug fixed ASAP, as in YESTERDAY! You've managed to turn entire plesk servers into insecure environment, how is this possible?
This is what we were using:
disable_functions = ini_alter,ini_restore,dl,system,exec,passthru,shell_exec,shell,proc_close,proc_open
and this is what we've got now:
disable_functions = "opcache_get_status"
Rubbish!
