CVE-2024-52402 is a security vulnerability classified as a Cross-Site Request Forgery (CSRF) affecting the gunghoinc Exclusive Content Password Protect plugin, specifically versions up to 1.1.0. The vulnerability enables an attacker to upload a web shell onto the web server hosting the plugin by exploiting the lack of proper CSRF protections. CSRF attacks manipulate authenticated users into performing unintended actions by sending forged HTTP requests, leveraging the victim's active session. In this case, the attacker crafts a malicious request that, when executed by an authenticated user, results in the upload of a web shell—a malicious script that provides remote control over the server. This vulnerability arises from insufficient validation of request authenticity, allowing state-changing operations without verifying the legitimacy of the request origin. Although no public exploits have been reported, the impact of such an attack is critical, as it can lead to complete server compromise, data theft, or further lateral movement within the network. The vulnerability affects all versions of the plugin up to 1.1.0, and no official patches or mitigations have been linked yet. The absence of a CVSS score indicates that the vulnerability is newly disclosed and requires immediate attention from users of the plugin. The attack vector requires the victim to be authenticated and to interact with a malicious webpage, which is typical for CSRF but still presents a high risk given the severity of the outcome.

The potential impact of CVE-2024-52402 is severe for organizations using the gunghoinc Exclusive Content Password Protect plugin. Successful exploitation allows attackers to upload web shells, effectively gaining remote code execution capabilities on the affected web server. This can lead to unauthorized access to sensitive data, defacement of websites, deployment of malware, or use of the compromised server as a pivot point for further attacks within the network. The integrity and availability of the web server and hosted applications can be severely compromised. Organizations relying on this plugin for content protection may face data breaches, loss of customer trust, and regulatory penalties. Since the vulnerability requires an authenticated user to be tricked into visiting a malicious page, organizations with many users or administrators are at higher risk. The absence of known exploits in the wild provides a window for proactive mitigation, but the critical nature of the vulnerability demands urgent remediation to prevent potential exploitation.

To mitigate CVE-2024-52402, organizations should immediately verify if they are using the gunghoinc Exclusive Content Password Protect plugin version 1.1.0 or earlier and plan to upgrade to a patched version once available. In the absence of an official patch, implement the following specific mitigations: 1) Enforce strict CSRF protections by adding nonce tokens or verifying the Origin and Referer headers on all state-changing requests within the plugin. 2) Restrict upload permissions to trusted users only and limit the types of files that can be uploaded to reduce the risk of web shell deployment. 3) Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious upload attempts or CSRF attack patterns targeting this plugin. 4) Educate users and administrators about the risks of CSRF and advise against clicking on untrusted links while authenticated. 5) Monitor web server logs for unusual upload activity or access to suspicious scripts. 6) Consider temporarily disabling the plugin if feasible until a secure version is released. These targeted actions go beyond generic advice and address the specific attack vector and impact of this vulnerability.
