CVE-2024-13601 in Majestic Support Plugin
Summary
by MITRE • 02/12/2025
The Majestic Support – The Leading-Edge Help Desk & Customer Support Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.0.5 via the 'exportusereraserequest' function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export ticket data for any user.

The Majestic Support plugin for WordPress presents a critical security vulnerability classified as Insecure Direct Object Reference under CVE-2024-13601. This vulnerability affects all versions up to and including 1.0.5, creating a significant risk for WordPress installations that rely on this customer support solution. The flaw manifests through the 'exportusereraserequest' function which fails to properly validate user-controlled input parameters, specifically a key that determines which user's ticket data can be exported. This design oversight allows authenticated attackers with subscriber-level privileges or higher to exploit the system and access ticket information belonging to other users within the same WordPress installation.
The technical implementation of this vulnerability stems from inadequate input validation mechanisms within the plugin's backend processing. When the 'exportusereraserequest' function processes export requests, it directly uses a user-controlled parameter without proper authorization checks or input sanitization. This allows malicious actors to manipulate the key parameter to reference any user account within the system, bypassing normal access controls that should restrict data access to authorized users only. The vulnerability operates at the application level and leverages the principle of least privilege violation, where the system fails to properly enforce access restrictions based on user roles and permissions.
From an operational impact perspective, this vulnerability creates a serious data exposure risk for organizations using the Majestic Support plugin. Attackers with subscriber-level access can potentially access sensitive customer support ticket data, including personal information, support requests, and communication history belonging to other users. This breach of data confidentiality can lead to privacy violations, regulatory compliance issues, and potential exploitation for further attacks such as social engineering or credential harvesting. The vulnerability is particularly concerning because it requires minimal privilege escalation to exploit, making it accessible to users who should normally have limited access to support data.
The vulnerability aligns with CWE-284, which describes Insecure Direct Object Reference, and represents a failure to properly implement access control mechanisms. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and data access, specifically T1078 for valid accounts and T1566 for credential harvesting. Organizations should immediately implement mitigation strategies including updating to the latest plugin version, implementing network segmentation, and monitoring for unauthorized access attempts. The recommended approach involves applying the vendor's patch as soon as it becomes available, while also considering temporary workarounds such as restricting user roles or implementing additional access controls at the WordPress level to prevent unauthorized data exports.
