Froxlor is open source server administration software. Prior to version 2.3.6, the Froxlor API endpoint `Customers.update` (and `Admins.update`) does not validate the `def_language` parameter against the list of available language files. An authenticated customer can set `def_language` to a path traversal payload (e.g., `../../../../../var/customers/webs/customer1/evil`), which is stored in the database. On subsequent requests, `Language::loadLanguage()` constructs a file path using this value and executes it via `require`, achieving arbitrary PHP code execution as the web server user. Version 2.3.6 fixes the issue.

GHSA-w59f-67xm-rxx7 — Froxlor has Local File Inclusion via path traversal in API `def_language` parameter leads to Remote Code Execution

Affected: Packagist: froxlor/froxlor

## Summary

The Froxlor API endpoint `Customers.update` (and `Admins.update`) does not validate the `def_language` parameter against the list of available language files. An authenticated customer can set `def_language` to a path traversal payload (e.g., `../../../../../var/customers/webs/customer1/evil`), which is stored in the database. On subsequent requests, `Language::loadLanguage()` constructs a file path using this value and executes it via `require`, achieving arbitrary PHP code execution as the web server user.

## Details

**Root cause:** The API and web UI have inconsistent validation for the `def_language` parameter.

The **web UI** (`customer_index.php:261`, `admin_index.php:265`) correctly validates `def_language` against `Language::getLanguages()`, which scans the `lng/` directory for actual language files:

```php // customer_index.php:260-265 $def_language = Validate::validate(Request::post('def_language'), 'default language'); if (isset($languages[$def_language])) { Customers::getLocal($userinfo, [ 'id' => $userinfo['customerid'], 'def_language' => $def_language ])->update(); ```

The **API** (`Customers.php:1207`, `Admins.php:600`) only runs `Validate::validate()` with the default regex `/^[^\r\n\t\f\0]*$/D`, which permits path traversal sequences:

```php // Customers.php:1167-1172 (customer branch) } else { // allowed parameters $def_language = $this->getParam('def_language', true, $result['def_language']); ... } // Cu…
