CVE-2024-49243 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP, commonly known as a Remote File Inclusion (RFI) vulnerability. It affects the Dynamic Elementor Addons plugin developed by ramjon27, specifically versions up to and including 1.0.0. The vulnerability occurs because the plugin fails to properly validate or sanitize user-supplied input used in PHP include or require statements. This flaw allows an attacker to manipulate the filename parameter to include arbitrary files from remote or local sources. Exploiting this vulnerability can enable an attacker to execute arbitrary PHP code on the server, leading to full system compromise. The vulnerability is particularly dangerous because it does not require authentication or user interaction, making it exploitable remotely by unauthenticated attackers. Although no public exploits have been reported yet, the nature of the vulnerability and the widespread use of WordPress and Elementor plugins make it a critical concern. The plugin is used to extend Elementor, a popular WordPress page builder, meaning many websites could be affected if they use this addon. The lack of a CVSS score indicates the need for manual severity assessment based on the technical details and potential impact.

The impact of CVE-2024-49243 is significant for organizations running WordPress websites that utilize the Dynamic Elementor Addons plugin. Successful exploitation can lead to remote code execution, allowing attackers to take full control over the affected web server. This can result in data theft, website defacement, installation of backdoors or malware, and use of the compromised server as a pivot point for further attacks within the network. The confidentiality, integrity, and availability of the affected systems are all at risk. For e-commerce, financial, healthcare, or government websites, the consequences can include loss of customer trust, regulatory penalties, and operational disruption. Since the vulnerability does not require authentication, it increases the attack surface and risk of automated exploitation attempts. Organizations with public-facing WordPress sites using this plugin are particularly vulnerable, and the threat can propagate quickly if not mitigated.

1. Immediately check if your WordPress site uses the Dynamic Elementor Addons plugin version 1.0.0 or earlier and plan to update to a patched version once available. 2. Until an official patch is released, disable or remove the vulnerable plugin to eliminate the attack vector. 3. Implement strict input validation and sanitization on any user inputs that may be used in include or require statements within custom code or plugins. 4. Configure PHP settings to disable remote file inclusion by setting 'allow_url_include' to 'Off' in php.ini. 5. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious requests attempting to exploit file inclusion vulnerabilities. 6. Monitor web server logs for unusual requests targeting the plugin or attempts to include remote files. 7. Conduct regular security audits and vulnerability scans on WordPress environments to detect outdated or vulnerable plugins. 8. Educate site administrators about the risks of installing unverified plugins and the importance of timely updates.
