CVE-2024-56286 is a path traversal vulnerability found in the Classic Addons – WPBakery Page Builder plugin developed by webcodingplace. The vulnerability arises from improper limitation of pathname inputs, allowing an attacker to traverse directories outside the intended restricted directory. This flaw enables PHP Local File Inclusion (LFI), where an attacker can include and execute arbitrary local files on the web server. The vulnerability affects all versions up to and including 3.0 of the plugin. By exploiting this issue, an attacker can potentially read sensitive files such as configuration files, password files, or other critical data stored on the server. In some cases, if the included files contain executable PHP code or if the attacker can upload malicious files, this could lead to remote code execution. The vulnerability does not currently have a CVSS score and no public exploits have been reported in the wild. However, the ease of exploitation—requiring only manipulation of input parameters without authentication or user interaction—makes it a significant risk. The affected product is a widely used WordPress page builder addon, which is commonly deployed in many websites globally. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability is categorized under path traversal and local file inclusion, both of which are critical web application security issues. Proper input validation and restricting file access paths are essential to prevent exploitation.

The impact of CVE-2024-56286 can be severe for organizations using the Classic Addons – WPBakery Page Builder plugin. Successful exploitation could lead to unauthorized disclosure of sensitive information such as database credentials, configuration files, or user data, compromising confidentiality. In some scenarios, it could allow attackers to execute arbitrary code on the server, leading to full system compromise, affecting integrity and availability. This could result in website defacement, data theft, or use of the compromised server as a pivot point for further attacks. Organizations relying on WordPress for their web presence, especially those using this plugin, face increased risk of targeted attacks. The vulnerability could also be leveraged to bypass security controls and escalate privileges within the web application environment. Given the widespread use of WordPress and its plugins, the potential attack surface is large, affecting small businesses to large enterprises. The absence of known exploits currently provides a window for remediation, but the risk remains high due to the nature of the vulnerability and the ease of exploitation.

To mitigate CVE-2024-56286, organizations should prioritize updating the Classic Addons – WPBakery Page Builder plugin to a patched version once available. Until a patch is released, implement strict input validation on all parameters that handle file paths to ensure they do not contain directory traversal sequences such as '../'. Employ web application firewalls (WAFs) with rules specifically designed to detect and block path traversal attempts. Restrict file permissions on the server to limit access to sensitive files and directories, ensuring the web server user has the minimum necessary privileges. Disable PHP functions that are not required and could be abused for file inclusion or code execution, such as include(), require(), and eval(), if possible. Monitor web server logs for suspicious requests attempting to access unusual file paths. Conduct regular security audits and penetration testing focused on file inclusion vulnerabilities. Additionally, consider isolating the web application environment using containerization or sandboxing to limit the impact of a potential compromise. Educate developers and administrators about secure coding practices related to file handling and path validation.
