AppConfig and Mod Security

BillyS · Jul 13, 2013

When working in WHM, in Home > Server Configuration > Tweak settings, if I set:

Allow apps that have not registered with AppConfig to be run when logged in as root or a reseller with the "all" ACL in WHM

To Off (since I'm assuming this is a more secure setting and the reason the feature was added...)

The Mod Security Add On Provides the following error:

HTTP error 401

cgi/addon_modsec.cgi

WHM is configured to disallow execution of unregistered applications when logged in as root or a reseller with the "all" ACL.

To enable this functionality you must do one of the following: Register this addon using /usr/local/cpanel/bin/register_appconfig (AppConfig), Enable the "Allow apps that have not registered with AppConfig to be run when logged in as root or a reseller with the "all" ACL in WHM" option in "Tweak Settings", or add permit_unregistered_apps_as_root=1 to /var/cpanel/cpanel.config, and run /usr/local/cpanel/etc/init/startcpsrvd

I'm not sure if the above really means Mod Security was turned off or it just wasn't accessable to me. I had just run EasyApache, so the Mod Security log was empty when I noticed the problem.

Is the above telling me the solution is as easy as running?:

Code:

/usr/local/cpanel/bin/register_appconfig /cgi/addon_modsec.cgi

I would like to know how to register this as well.

HTTP error 401
cgi/addon_modsec.cgi

WHM is configured to disallow execution of unregistered applications when logged in as root or a reseller with the "all" ACL. To enable this functionality you must do one of the following: Register this addon using /usr/local/cpanel/bin/register_appconfig (AppConfig), Enable the "Allow apps that have not registered with AppConfig to be run when logged in as root or a reseller with the "all" ACL in WHM" option in "Tweak Settings", or add permit_unregistered_apps_as_root=1 to /var/cpanel/cpanel.config, and run /usr/local/cpanel/etc/init/startcpsrvd

Please advise!

ModSecurity was not turned off, but you could not access addon_modsec.

No, to register it you need a config file, see here:
AppConfig

quietFinn -

That's where I was looking... I'm on 11.38.1+, so I'm looking at these instructions:

Once 11.38.1+ is available, you should refrain from installing your app config manually. You should use the new tools available:

/usr/local/cpanel/bin/register_appconfig <appconfig_file>

That's why I was suggestion this:

Code:

/usr/local/cpanel/bin/register_appconfig /cgi/addon_modsec.cgi

quietFinn · Jul 14, 2013

/usr/local/cpanel/bin/register_appconfig <appconfig_file>

<appconfig_file> is the configuration file for the application you are registering.

and what would be the conf file for this application?

thnx

This should work, file addon_modsec.conf in /var/cpanel/apps:

Code:

# name
name=addon_modsec

# Service that will serve this app
service=whostmgr
 
# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/addon_modsec.cgi
 
# System user to run process as
user=root

# Required acls
acls=any

# Display name as show in the service ui
displayname=addon_modsec

then just run:

Code:

/usr/local/cpanel/bin/register_appconfig addon_modsec.conf

cPanelMichael · Jul 15, 2013

Yes, the example in the previous post will register the Mod_Security plugin with AppConfig. I tested this on a server and confirmed it works as expected. To note, there is an internal case open to address the AppConfig registration of plugins that are distributed with cPanel/WHM. For reference, the case number is 72993. It's not yet been determined if any changes in the behavior will be implemented.

Thank you.

That worked.

I am having issue with clamv as well.

cgi/addon_clamavconnector.cgi

WHM is configured to disallow execution of unregistered applications when logged in as root or a reseller with the "all" ACL. To enable this functionality you must do one of the following: Register this addon using /usr/local/cpanel/bin/register_appconfig (AppConfig), Enable the "Allow apps that have not registered with AppConfig to be run when logged in as root or a reseller with the "all" ACL in WHM" option in "Tweak Settings", or add permit_unregistered_apps_as_root=1 to /var/cpanel/cpanel.config, and run /usr/local/cpanel/etc/init/startcpsrvd

Could you PLEASE help with this one?

Thanks

cPanelMichael · Jul 15, 2013

You should be able to use the same method for registering the ClamAV plugin that was used for Mod_Security. Simply update the file names to match the ClamAV plugin.

Thank you.

Daky · Jul 15, 2013

Worked, thanks

BillyS · Jul 15, 2013

Thanks quietFinn and CPanelMichael, I'll give this a try too.

Hello QuietFinn,
I am trying to create an addon_rvsitebuilder.conf with the following commands in the file:

# name
name=rvsitebuilder

# Service that will serve this app
service=whostmgr

# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/addon_rvsitebuilder.cgi

# System user to run process as
user=root

# Required acls
acls=any

# Display name as show in the service ui
displayname=RVSiteBuilder

# Url to show in the service ui (relative to install path for whm this is cgi/)
entryurl=rvsitebuilder/index.php

But now it shows:
HTTP error 401
cgi/rvsitebuilder/index.php

What I have missed here?

Thanks in advance for your help.

Regards,

Sergio

quietFinn · Aug 1, 2013

You have the line:

entryurl=rvsitebuilder/index.php

Is that correct?

entryurl is optional key so you could try without it.

Hello QuietFinn,
finally I managed to set the correct conf file for RVSBuilder, just in case someone needs it:

# name
name=rvsitebuilder

# Service that will serve this app
service=whostmgr

# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/addon_rvsitebuilder.cgi
url2=/cgi/rvsitebuilder/setup.php
url3=/cgi/rvsitebuilder/index.php
url4=/cgi/rvsitebuilder/optimizer.php
url5=/cgi/rvsitebuilder/themes/default/sitebuilder/css/style.php
url6=/cgi/rvsitebuilder/themes/default_admin/sitebuilder/css/style.php
url7=/cgi/rvsitebuilderinstaller/index.php
url8=/cgi/rvsitebuilderinstaller/templates/installer.php
url9=/cgi/rvsitebuilder/themes/default/css/installer.php

# System user to run process as
user=root

# Required acls
acls=any

# Display name as show in the service ui
displayname=RVSiteBuilder

Thanks to the RVSB team for giving me all the URLs needed for this to work.

Just in case someone needs the conf file for RVSKIN, here are the commands:

# name
name=rvskin

# Service that will serve this app
service=whostmgr

# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/rvskinmanager/index.cgi
url2=/cgi/rvskinmanager/Rvbranding.cgi
url3=/cgi/rvskinmanager/rvDisableCpanelpackageFeatures.cgi
url4=/cgi/rvskinmanager/rvMainFtp.cgi
url5=/cgi/rvskinmanager/rvskinclearcache.cgi
url6=/cgi/rvskinmanager/Rvskinmanager.cgi
url7=/cgi/rvskinmanager/rvskinnewsmysql.cgi
url8=/cgi/addon_rvskinmanager.cgi

# System user to run process as
user=root

# Required acls
acls=any

# Display name as show in the service ui
displayname=RVSkin

Thanks to the RVSB team for giving me all the URLs needed for this to work.

Now I just need the Fantastico commands...

When I try to run

Code:

/usr/local/cpanel/bin/register_appconfig addon_modsec.conf

I get

The 'conf_file' must be readable and a plain file.

Anyone else getting this?

cPanelMichael · Sep 19, 2013

Have you created the addon_modsec.conf file in the /var/cpanel/apps directory?

Thank you.
