REDAXO is a PHP-based content management system. Prior to 5.21.2, rex_api_install_package_update in redaxo/src/addons/install/lib/api/api_package_update.php inherits the false default from rex_api_function::requiresCsrfProtection() instead of requiring a CSRF token. An unauthenticated attacker can cause a logged-in administrator's browser to request a selected package update from the configured REDAXO package server, changing installed addon code or disrupting the site without the administrator's intent. This issue is fixed in version 5.21.2.
REDAXO: Unwhitelisted ORDER BY Column in rex_list Allows Authenticated Column Enumeration
REDAXO is a PHP-based content management system. Prior to 5.21.2, rex_list::getSortColumn() in redaxo/src/core/lib/list.php accepts the sort request parameter without checking whether setColumnSortable() registered the requested column. An authenticated backend user can make prepareQuery() add an escaped but unauthorized ORDER BY identifier, allowing error-based enumeration of columns in joined tables and ordering by unselected sensitive fields such as rex_user.password. This issue is fixed in version 5.21.2.

REDAXO: Stored XSS in Mediapool Sync Page via Unescaped Filesystem Filenames
REDAXO is a PHP-based content management system. Prior to 5.21.2, redaxo/src/addons/mediapool/pages/sync.php inserts filenames held in $diffFiles from the media filesystem into the Mediapool Sync page without rex_escape(). An attacker who can place an unregistered file with HTML metacharacters in the media directory can execute script in the browser of a backend user with media[sync] permission when that user opens the Sync page, enabling session theft or unauthorized backend actions. This issue is fixed in version 5.21.2.

REDAXO: Stored XSS via Unescaped Media Manager Type Name in `mediaIsInUse()`
REDAXO is a PHP-based content management system. Prior to 5.21.2, the mediaIsInUse() handler in redaxo/src/addons/media_manager/lib/media_manager.php inserts a Media Manager type name into raw backend warning HTML without escaping it when invoked through MEDIA_IS_IN_USE. An administrator with Media Manager access can store HTML in a type name, and the payload executes in another administrator's browser when that administrator tries to delete media referenced by the type's effects, enabling session theft or unauthorized backend actions. This issue is fixed in version 5.21.2.
Redaxo has a Mediapool isAllowedExtension bypass via multi-segment filename that leads to authenticated RCE on Apache mod_php multi-extension handlers
REDAXO is a PHP-based content management system. From 5.18.2 until 5.21.1, rex_mediapool::isAllowedExtension in redaxo/src/addons/mediapool/lib/mediapool.php lets an authenticated backend user with media[upload] permission upload a JPEG/PHP polyglot named shell.php.any.jpg, which web servers with multi-extension PHP handlers can execute as the web-server user. This issue is fixed in version 5.21.1.
REDAXO has reflected XSS backend packages API via function parameter (CSRF token required)
### Summary
A **reflected XSS** vulnerability has been identified in the REDAXO backend. The `function` parameter is concatenated into an API error message and rendered without HTML escaping.
---
### Details
**Root cause**
User input `function` is injected into an exception message, then rendered by `rex_view::error()` which delegates to `rex_view::message()` without HTML escaping.
**Vulnerable code (`redaxo/src/core/lib/packages/api_package.php`) :**
```php
$function = rex_request('function', 'string');
throw new rex_api_exception('Unknown package function "' . $function . '"!');
```
**Sink (`redaxo/src/core/lib/view.php`) :**
```php
REDAXO has reflected XSS in backend Metainfo API via type parameter (CSRF token required)
### Summary
A **reflected XSS** vulnerability has been identified in the REDAXO backend. The `type` parameter is concatenated into an API error message and rendered without HTML escaping.

### Details
**Root cause**
User input `type` is injected into an exception message, then rendered by `rex_view::error()` which delegates to `rex_view::message()` without HTML escaping.
**Vulnerable code (`redaxo/src/addons/metainfo/lib/handler/api_default_fields.php`) :**
```php
$type = rex_get('type', 'string');
throw new rex_api_exception(sprintf('metainfo type "%s" does not have default field.', $type));

Redaxo has Path Traversal in Backup Addon Leading to Arbitrary File Read
REDAXO is a PHP-based content management system. Prior to version 5.20.2, authenticated users with backup permissions can read arbitrary files within the webroot via path traversal in the Backup addon's file export functionality. The Backup addon does not validate the `EXPDIR` POST parameter against the UI-generated allowlist of permitted directories. An attacker can supply relative paths containing `../` sequences (or even absolute paths inside the document root) to include any readable file in the generated `.tar.gz` archive. Version 5.20.2 fixes this issue.
REDAXO is Vulnerable to Reflected XSS in Mediapool Info Banner via args[types]
REDAXO is a PHP-based CMS. Prior to version 5.20.1, a reflected Cross-Site Scripting (XSS) vulnerability exists in the Mediapool view where the request parameter args[types] is rendered into an info banner without HTML-escaping. This allows arbitrary JavaScript execution in the backend context when an authenticated user visits a crafted link while logged in. This issue has been patched in version 5.20.1.
A Remote Code Execution (RCE) vulnerability in the template management component in REDAXO CMS 5.20.0 allows remote authenticated administrators to execute arbitrary operating system commands by injecting PHP code into an active template. The payload is executed when visitors access frontend pages using the compromised template.
A stored cross-site scripting (XSS) vulnerability in the module management component in REDAXO CMS 5.20.0 allows remote users to inject arbitrary web script or HTML via the Output code field in modules. The payload is executed when a user views or edits an article by adding slice that uses the compromised module.
REDAXO allows Authenticated Reflected Cross Site Scripting - packages installation
REDAXO is a PHP-based CMS. In Redaxo from 5.0.0 through 5.18.2, the rex-api-result parameter is vulnerable to Reflected cross-site scripting (XSS) on the page of AddOns. This vulnerability is fixed in 5.18.3.
REDAXO allows Arbitrary File Upload in the mediapool page
REDAXO is a PHP-based CMS. In Redaxo before 5.18.3, the mediapool/media page is vulnerable to arbitrary file upload. This vulnerability is fixed in 5.18.3.
Redaxo CMS Structure Management Page index.php cross site scripting
A vulnerability was found in Redaxo CMS 5.18.1. It has been classified as problematic. Affected is an unknown function of the file /index.php?page=structure&category_id=1&article_id=1&clang=1&function=edit_art&artstart=0 of the component Structure Management Page. The manipulation of the argument Article Name leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting (XSS) vulnerability in the component /media/test.html of REDAXO CMS v5.17.1 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the password parameter.
The mediapool feature of the Redaxo Core CMS application v 5.17.1 is vulnerable to Cross Site Scripting(XSS) which allows a remote attacker to escalate privileges
