CVE-2024-3593 in UberMenu Plugin
Summary
by MITRE • 06/22/2024
The UberMenu plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.3. This is due to missing or incorrect nonce validation on the ubermenu_delete_all_item_settings and ubermenu_reset_settings functions. This makes it possible for unauthenticated attackers to delete and reset the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The vulnerability identified in CVE-2024-3593 affects the UberMenu plugin for WordPress, a popular navigation menu solution that allows administrators to create complex and customizable navigation structures for websites. This particular flaw represents a critical security weakness that undermines the integrity of the plugin's administrative functions and poses significant risks to WordPress sites utilizing this component. The vulnerability specifically targets the plugin's ability to manage its own configuration settings, creating a potential attack vector that could lead to complete administrative compromise of affected systems.
The technical implementation of this vulnerability stems from the absence of proper nonce validation within two critical functions: ubermenu_delete_all_item_settings and ubermenu_reset_settings. Nonce validation serves as a cryptographic token that ensures requests originate from legitimate administrative users and prevents unauthorized modifications to system configurations. When these validation mechanisms are absent or improperly implemented, attackers can forge requests that appear to come from authenticated administrators. The vulnerability exists across all versions up to and including 3.8.3, indicating that the flaw has persisted for an extended period without proper remediation.
From an operational perspective, this CSRF vulnerability creates a severe risk landscape for affected WordPress installations. An unauthenticated attacker can exploit this weakness by crafting malicious requests that, when executed by an administrator, will delete all menu item settings or reset the plugin configuration to default values. This could result in complete loss of custom navigation configurations, potentially disrupting website functionality and requiring significant administrative effort to restore. The attack requires social engineering to trick administrators into clicking malicious links, but once successful, it can cause substantial operational disruption and may provide attackers with additional opportunities for further compromise.
The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery flaws in software applications. This classification emphasizes the fundamental nature of the weakness as an authentication bypass mechanism that allows attackers to perform actions on behalf of authenticated users without their knowledge or consent. From an ATT&CK framework perspective, this vulnerability maps to T1078.004, which covers valid accounts and T1566, which addresses credential harvesting through social engineering techniques. The attack chain typically involves the initial compromise through phishing or malicious link delivery, followed by the execution of administrative functions that modify critical plugin configurations.
Organizations should immediately update to the latest version of the UberMenu plugin where this vulnerability has been properly addressed through the implementation of proper nonce validation mechanisms. System administrators should also implement additional security measures including regular security audits of installed plugins, monitoring for unauthorized configuration changes, and educating administrators about social engineering threats. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, though the primary mitigation remains the immediate patching of affected systems. The vulnerability demonstrates the critical importance of maintaining up-to-date security practices and the potential consequences of delayed patch management in WordPress environments.
