CVE-2024-13432 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the sjhand Webcamconsult plugin for WordPress, affecting all versions up to and including 1.5.0. The vulnerability stems from missing or incorrect nonce validation on a critical function within the plugin. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. Without proper nonce checks, attackers can craft malicious web requests that, when executed by an authenticated administrator (typically via clicking a link), cause unauthorized changes to plugin settings or inject malicious scripts into the site. This can lead to compromise of site integrity and partial confidentiality loss, as attackers may manipulate plugin behavior or inject code that affects site visitors or administrators. The vulnerability requires no prior authentication but does require user interaction, specifically that an administrator is tricked into clicking a malicious link. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, with low confidentiality and integrity impact and no availability impact. No public exploits are known at this time, but the vulnerability is published and should be addressed promptly. The plugin is used in WordPress environments, which are widely deployed globally, especially in small to medium business and healthcare sectors where Webcamconsult may be used for teleconsultation services.

The primary impact of this vulnerability is unauthorized modification of plugin settings and potential injection of malicious scripts, which can compromise the integrity of the affected WordPress site. This can lead to unauthorized administrative actions, defacement, or further exploitation such as persistent cross-site scripting (XSS). Confidentiality may be partially impacted if injected scripts capture sensitive data or session tokens. Availability is not directly affected. Organizations relying on Webcamconsult for teleconsultation or video communication may face disruption or reputational damage if attackers exploit this flaw. Since exploitation requires tricking an administrator, social engineering is a key risk factor. The vulnerability affects all sites using the vulnerable plugin versions worldwide, potentially exposing healthcare providers, telemedicine platforms, and other organizations using this plugin to targeted attacks. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure.

Organizations should monitor for and apply patches or updates from the sjhand Webcamconsult plugin vendor as soon as they become available. In the absence of an official patch, administrators can implement manual nonce validation on affected plugin functions to ensure requests are legitimate. Web administrators should restrict administrative access to trusted networks or VPNs to reduce exposure. Educating site administrators about the risks of clicking unsolicited links and implementing multi-factor authentication (MFA) for WordPress admin accounts can reduce the likelihood of successful exploitation. Employing web application firewalls (WAFs) with rules to detect and block CSRF attempts or suspicious requests targeting the plugin endpoints can provide additional protection. Regular security audits and monitoring for unusual administrative actions or injected scripts are recommended. Finally, limiting plugin usage to trusted and necessary environments reduces attack surface.
