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.

Affected: Packagist: admidio/admidio

### Summary

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. The vulnerability is present in the latest version, 4.3.16.

### Details

The vulnerability is located in the `adm_program/modules/groups-roles/members_assignment_data.php` script. This script handles an AJAX request to fetch a list of users for role assignment. The `filter_rol_uuid` GET parameter is not properly sanitized before being used in a raw SQL query.

**File:** `adm_program/modules/groups-roles/members_assignment_data.php` ```php // ... // The parameter is retrieved from the GET request without sufficient sanitization for SQL context. $getFilterRoleUuid = admFuncVariableIsValid($_GET, 'filter_rol_uuid', 'string'); $getMembersShowAll = admFuncVariableIsValid($_GET, 'mem_show_all', 'bool', array('defaultValue' => false));

// ... $filterRoleCondition = ''; if ($getMembersShowAll) { $getFilterRoleUuid = 0; } else { // show only members of current organization if ($getFilterRoleUuid !== '') { // VULNERABLE CODE: $getFilterRoleUuid is directly concatenated into the query string. $filterRoleCondition = ' AND rol_uuid = \''.$getFilterRoleUu…
