Admidio: >> Admidio Security Vulnerabilities
Admidio is an open-source user management solution. In versions 5.0.0 through 5.0.6, the delete, activate, and deactivate modes in modules/groups-roles/groups_roles.php perform destructive state changes on organizational roles but never validate an anti-CSRF token. The client-side UI passes a CSRF token to callUrlHideElement(), which includes it in the POST body, but the server-side handlers ignore $_POST["adm_csrf_token"] entirely for these three modes. An attacker who can discover a role UUID (visible in the public cards view when the module is publicly accessible) can embed a forged POST form on any external page and trick any user with the rol_assign_roles right into deleting or toggling roles for the organization. Role deletion is permanent and cascades to all memberships, event associations, and rights data. If exploited, an attacker can trick any user with delegated role-assignment rights into permanently deleting roles, mass-revoking all associated memberships and access to events, documents, and mailing lists, or silently activating or deactivating entire groups, with target role UUIDs trivially harvested from the unauthenticated public cards view and no undo path short of a database restore. This issue has been fixed in version 5.0.7.

Admidio is an open-source user management solution. In versions 5.0.0 through 5.0.6, the forum module in Admidio does not verify whether the current user has permission to delete forum topics or posts. Both the topic_delete and post_delete actions in forum.php only validate the CSRF token but perform no authorization check before calling delete(). Any authenticated user with forum access can delete any topic (with all its posts) or any individual post by providing its UUID. This is inconsistent with the save/edit operations, which properly check isAdministratorForum() and ownership before allowing modifications. Any logged-in user can permanently and irreversibly delete any forum topic (including all its posts) or any individual post by simply knowing its UUID (which is publicly visible in URLs), completely bypassing authorization checks. This issue has been fixed in version 5.0.7.

Admidio is an open-source user management solution. Prior to 5.0.6, in modules/events/events_function.php, the event participation logic allows any user who can participate in an event to register OTHER users by manipulating the user_uuid GET parameter. The condition uses || (OR), meaning if possibleToParticipate() returns true (event is open for participation), ANY user - not just leaders - can specify a different user_uuid and register/cancel participation for that user. The code then operates on $user->getValue('usr_id') (the target user from user_uuid) rather than the current user. This vulnerability is fixed in 5.0.6.

Admidio is an open-source user management solution. Prior to version 4.3.17, an authenticated SQL injection vulnerability exists in the member assignment data retrieval functionality of Admidio. Any authenticated user with permissions to assign members to a role (such as an administrator) can exploit this vulnerability to execute arbitrary SQL commands. This can lead to a full compromise of the application's database, including reading, modifying, or deleting all data. This issue has been patched in version 4.3.17.

Admidio is a free, open source user management system for websites of organizations and groups. In Admidio before version 4.3.9, there is an SQL Injection in the `/adm_program/modules/ecards/ecard_send.php` source file of the Admidio Application. The SQL Injection results in a compromise of the application's database. The value of `ecard_recipients `POST parameter is being directly concatenated with the SQL query in the source code causing the SQL Injection. The SQL Injection can be exploited by a member user, using blind condition-based, time-based, and Out of band interaction SQL Injection payloads. This vulnerability is fixed in 4.3.9.

Admidio is a free, open source user management system for websites of organizations and groups. In Admidio before version 4.3.10, there is a Remote Code Execution Vulnerability in the Message module of the Admidio Application, where it is possible to upload a PHP file in the attachment. The uploaded file can be accessed publicly through the URL `{admidio_base_url}/adm_my_files/messages_attachments/{file_name}`. The vulnerability is caused due to the lack of file extension verification, allowing malicious files to be uploaded to the server and public availability of the uploaded file. This vulnerability is fixed in 4.3.10.
