See Permissions for information about the permissions system in Ibexa DXP.
See the Security checklist for a list of security-related issues you should take care of before going live with a project.
To use Symfony authentication with Ibexa DXP, use the following configuration (in
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7
You can fully customize the routes and/or the controller used for login.
However, remember to match
Authentication using Symfony Security component¶
Authentication is provided using the Symfony Security component.
Native and universal
form_login is used, in conjunction with an extended
DaoAuthenticationProvider (DAO stands for Data Access Object), the
RepositoryAuthenticationProvider. Native behavior of
DaoAuthenticationProvider has been preserved, making it possible to still use it for pure Symfony applications.
SecurityController is used to manage all security-related actions and is thus used to display the login form. It follows all standards explained in Symfony security documentation.
The base template used is
The layout used by default is
%ezpublish.content_view.viewbase_layout% (empty layout) but can be configured together with the login template:
1 2 3 4 5 6
Redirection after login¶
By default, Symfony redirects to the URI configured in
default_target_path. If not set, it defaults to
It is possible to use the "Remember me" functionality. Refer to the Symfony cookbook on this topic.
If you want to use this feature, you must at least extend the login template in order to add the required checkbox:
1 2 3 4 5 6 7
Login handlers / SSO¶
Symfony provides native support for multiple user providers. This makes it easy to integrate any kind of login handlers, including SSO and existing third-party bundles (e.g. FR3DLdapBundle, HWIOauthBundle, FOSUserBundle, BeSimpleSsoAuthBundle, etc.).
See Authenticating a user with multiple user provider for more information.
To use JWT authentication with eZ Platform, in the provided
modify the existing configuration by setting
1 2 3 4 5 6 7 8 9 10 11 12
You also need a new Symfony firewall configuration for REST and/or GraphQL APIs.
It is already provided in
config/packages/security.yaml, you only need to uncomment it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
Executable packages with Legacy Bridge¶
This issue affects installations using eZ Publish Legacy, either stand-alone, or as part of eZ Platform 5.x, or in eZ Platform 1.11 and newer using LegacyBridge. If you are not using Legacy in any way, you are not affected.
The package system, by design, allows you to package an extension into a file, and export/import such packages. Extensions can of course contain PHP scripts, and they usually do. Such scripts can be used in an attack on the server. This problem is fundamental and cannot be fixed by any other means than by removing the feature.
By default, only the Administrator has the permissions to use the package system. It follows that the Administrator role, and any others granted packaging permissions, can only be held by users who already have access to the server, and/or can be trusted not to exploit this access.
As a consequence eZ Publish legacy should not be used in the type of shared hosting installation where Administrators are not supposed to have access to the underlying operating system, or to other eZ Publish installations on the same server. The package system is an old part of eZ Publish legacy, and it was not designed for that kind of installation. Currently this is not considered best practice anyway - setups using e.g. Docker and Platform.sh allow you to completely separate installations from each other. This is a better way to keep things secure than relying on PHP scripts being read-only even for administrators. (The package system does not exist in Ibexa DXP and will not be added there, since extensions are not used there.)
If you are responsible for legacy installations where administrators cannot be fully trusted not to exploit their privileges, make sure to properly lock down the package system and/or fully separate web sites from each other. Make sure that the administrator password(s) are secure, and not using the default administrator password.
Proposed quick solution for those affected:
If you are administrating a shared hosting solution of this kind, it may take a while to change the setup. Meanwhile, one quick way to lock down the package system is to use rewrite rules to block all access to package URLs. Apache example:
RewriteRule ^/package/.* - [R=403,L]
or with URL-based SiteAccess:
RewriteRule ^/my_site_access/package/.* - [R=403,L]
or supporting both cases, and multiple SiteAccesses:
RewriteRule ^(/my_site_access|/my_site_access_admin)?/package/.* - [R=403,L]
This can be placed before other rules.
To be absolutely certain you can also (or instead of this) delete the
/kernel/package directory in the eZ Publish web root. Please note that this will break the legacy installation wizard, since it relies on the package system to install the demo design.
Once the situation is resolved these measures should be reversed, to bring back the package features. You may want to do a review of whether the issue may have been exploited on your server(s).
