Missing Authorization vulnerability in mndpsingh287 File Manager allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects File Manager: from n/a through 7.2.7.

The Frontend File Manager (versions < 4.0), N-Media Post Front-end Form (versions < 1.1) plugins for WordPress are vulnerable to arbitrary file uploads due to missing file type validation via the `nm_filemanager_upload_file` and `nm_postfront_upload_file` AJAX actions. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

The File Manager Pro plugin for WordPress is vulnerable to Limited JavaScript File Upload in all versions up to, and including, 8.3.9. This is due to a lack of proper checks on allowed file types. This makes it possible for unauthenticated attackers, with permissions granted by an administrator, to upload .css and .js files, which could lead to Stored Cross-Site Scripting.

The File Manager Pro plugin for WordPress is vulnerable to arbitrary backup file downloads and uploads due to missing file type validation via the 'mk_file_folder_manager_shortcode' ajax action in all versions up to, and including, 8.3.9. This makes it possible for unauthenticated attackers, if granted access to the File Manager by an administrator, to download and upload arbitrary backup files on the affected site's server which may make remote code execution possible.

The File Manager Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 8.3.9. This is due to missing or incorrect nonce validation on the 'mk_file_folder_manager' ajax action. This makes it possible for unauthenticated attackers to upload arbitrary files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The File Manager plugin for WordPress is vulnerable to authorization bypass due to a missing capability check in the /inc/root.php file in versions up to, and including, 3.0. This makes it possible for unauthenticated attackers to download arbitrary files from the server and upload arbitrary files that can be used for remote code execution.

The Bit File Manager – 100% Free & Open Source File Manager and Code Editor for WordPress plugin for WordPress is vulnerable to Limited JavaScript File Upload in all versions up to, and including, 6.5.7. This is due to a lack of proper checks on allowed file types. This makes it possible for authenticated attackers, with Subscriber-level access and above, and granted permissions by an administrator, to upload .css and .js files, which could lead to Stored Cross-Site Scripting.

Multiple plugins and/or themes for WordPress are vulnerable to Limited File Upload in various versions. This is due to a lack of proper checks to ensure lower-privileged roles cannot upload .css and .js files to arbitrary directories. This makes it possible for authenticated attackers, with Subscriber-level access and above, and granted permissions by an administrator, to upload .css and .js files to any directory within the WordPress root directory, which could lead to Stored Cross-Site Scripting. The Advanced File Manager Shortcodes plugin must be installed to exploit this vulnerability.

The Advanced File Manager plugin for WordPress is vulnerable to Local JavaScript File Inclusion in all versions up to, and including, 5.2.8 via the 'fma_locale' parameter. This makes it possible for authenticated attackers, with Administrator-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
