CVE-2024-53824 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the All Bootstrap Blocks plugin for PHP-based applications. This vulnerability allows a Remote File Inclusion (RFI) attack, where an attacker can manipulate the filename parameter used in PHP include or require statements to load malicious remote files. The affected versions include all releases up to and including 1.3.19. The root cause is insufficient validation or sanitization of user-supplied input controlling the file path, enabling attackers to specify arbitrary remote URLs. Successful exploitation can lead to remote code execution on the server, allowing attackers to execute arbitrary PHP code, potentially leading to full system compromise, data theft, or defacement. The vulnerability does not require authentication, increasing its risk profile. Although no public exploits are currently known, the nature of RFI vulnerabilities makes them attractive targets for attackers. The vulnerability was published on December 6, 2024, and no CVSS score has been assigned yet. The plugin is commonly used in PHP environments that rely on Bootstrap blocks for UI components, often within WordPress or similar CMS ecosystems.

The impact of CVE-2024-53824 is significant for organizations using the All Bootstrap Blocks plugin in PHP environments. Remote File Inclusion vulnerabilities can lead to remote code execution, which allows attackers to run arbitrary code on the affected server. This can result in full system compromise, data breaches, unauthorized access to sensitive information, defacement of websites, and use of the compromised server as a pivot point for further attacks. The vulnerability's lack of authentication requirement and potential ease of exploitation increase the risk of widespread exploitation. Organizations hosting customer data, financial information, or critical infrastructure services using this plugin are particularly at risk. Additionally, compromised servers can be used to distribute malware or conduct further attacks, amplifying the threat. The absence of known exploits currently provides a window for remediation, but the risk remains high due to the vulnerability class.

1. Immediately update the All Bootstrap Blocks plugin to a version that patches this vulnerability once it is released by the vendor. 2. Until a patch is available, apply strict input validation and sanitization on all parameters that control file inclusion paths to ensure only allowed local files can be included. 3. Disable allow_url_include in the PHP configuration (php.ini) to prevent inclusion of remote files via include or require statements. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block suspicious file inclusion attempts. 5. Conduct code reviews and audits of custom PHP code to identify and remediate unsafe include/require usage. 6. Monitor web server logs for unusual requests that attempt to exploit file inclusion vulnerabilities. 7. Implement least privilege principles on the web server to limit the impact of a successful exploit. 8. Educate developers and administrators about secure coding practices related to file inclusion and input validation.
