Summary
by MITRE • 10/17/2022
The miniOrange Discord Integration WordPress plugin before 2.1.6 does not have authorisation and CSRF in some of its AJAX actions, allowing any logged in users, such as subscriber to call them, and disable the app for example

The miniOrange Discord Integration WordPress plugin version 2.1.5 and earlier contains critical authorization and cross-site request forgery vulnerabilities that expose the plugin to unauthorized manipulation by low-privileged users. This vulnerability specifically affects AJAX actions within the plugin's functionality, creating a pathway for authenticated users with minimal privileges to execute administrative operations without proper authorization. The flaw stems from insufficient validation of user permissions and lack of CSRF protection mechanisms in critical backend endpoints, allowing any logged-in user including subscribers to perform actions that should be restricted to administrators or higher privileged roles. This represents a classic privilege escalation vulnerability where a user with limited access can leverage the plugin's functionality to compromise the application's integrity and availability.
The technical implementation of this vulnerability involves the plugin's AJAX handlers failing to verify whether the requesting user possesses sufficient privileges to execute specific administrative functions. When users with subscriber-level access make requests to these unprotected endpoints, they can trigger operations such as disabling the entire Discord integration application, effectively causing a denial of service condition for legitimate administrators who rely on this plugin for communication integration. The absence of CSRF tokens in these AJAX actions means that malicious actors can craft requests that appear legitimate to the WordPress application, as the session authentication is sufficient to bypass the authorization checks. This vulnerability directly maps to CWE-863, which describes "Authorization Bypass Through User-Controlled Key" and aligns with ATT&CK technique T1078.004, "Valid Accounts: Cloud Accounts," as it allows privilege escalation through legitimate user accounts.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it can lead to complete service disruption of the Discord integration functionality within WordPress environments. Attackers can disable the plugin entirely, preventing legitimate administrators from maintaining communication channels with their Discord servers, while simultaneously gaining the ability to manipulate other plugin settings that might affect the overall WordPress site functionality. The vulnerability affects WordPress installations where the miniOrange plugin is active, creating a persistent threat vector that remains active until the plugin is updated to version 2.1.6 or later. Organizations using this plugin without proper monitoring or access controls face significant risk of unauthorized modifications to their communication infrastructure, potentially leading to data loss or service interruption. The attack surface is particularly concerning in multi-user WordPress environments where subscriber accounts might be compromised or where users have elevated privileges through other means.
Organizations should immediately update to miniOrange plugin version 2.1.6 or later to address this vulnerability, as the fix implements proper authorization checks and CSRF protection mechanisms for all AJAX endpoints. System administrators should also implement monitoring solutions to detect unauthorized access attempts to plugin administrative functions and consider implementing additional access controls or role restrictions for users who do not require full administrative privileges. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and filtering requests to known vulnerable endpoints. The vulnerability highlights the importance of proper input validation and authorization checks in WordPress plugin development, emphasizing that all user-facing functionality should validate permissions and implement CSRF protection to prevent unauthorized operations. Security teams should also conduct comprehensive audits of all installed plugins to identify similar authorization flaws and ensure that all administrative functions require proper authentication and authorization before execution.
