The CVE-2024-43281 vulnerability represents a critical path traversal flaw in the VOID CODERS Void Elementor Post Grid Addon for Elementor Page builder, specifically impacting versions ranging from n/a through 2.3. This vulnerability stems from improper limitation of pathname to a restricted directory, creating a dangerous condition where user input is not adequately sanitized before being used in file operations. The flaw allows attackers to manipulate file paths through the addon's PHP processing mechanisms, potentially enabling unauthorized access to sensitive system files and resources.
The technical implementation of this vulnerability occurs within the addon's file handling routines where user-supplied parameters are directly incorporated into file system operations without proper validation or sanitization. When the addon processes requests containing crafted path parameters, it fails to restrict file access to predefined directories, allowing attackers to traverse the file system hierarchy and access files outside the intended scope. This weakness specifically manifests in PHP local file inclusion scenarios where malicious path manipulation can lead to arbitrary code execution or information disclosure.
The operational impact of this vulnerability extends beyond simple file access, as it creates a potential pathway for attackers to escalate privileges and compromise the entire WordPress installation. An attacker could leverage this flaw to access configuration files containing database credentials, wp-config.php files, or other sensitive system information. Additionally, the vulnerability may enable attackers to upload malicious files or execute arbitrary PHP code, potentially leading to full system compromise and persistent backdoor access. The vulnerability affects the core functionality of the Elementor page builder, making it particularly dangerous in environments where multiple users have access to the admin interface.
Security professionals should consider this vulnerability in the context of CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory, and aligns with ATT&CK technique T1059.007 for PHP code injection. The vulnerability demonstrates the critical importance of input validation and proper file access controls in web applications. Organizations should immediately update to the latest version of the Void Elementor Post Grid Addon or implement temporary mitigations such as restricting file upload capabilities, implementing proper input sanitization, and monitoring for suspicious file access patterns. Network segmentation and firewall rules can also provide additional protection layers against exploitation attempts.
