CVE-2024-7514 in Comments Import & Export Plugin
Summary
by MITRE • 10/11/2024
The WordPress Comments Import & Export plugin for WordPress is vulnerable to to arbitrary file read due to insufficient file path validation during the comments import process, in versions up to, and including, 2.3.7. This makes it possible for authenticated attackers, with Author-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The issue was partially fixed in version 2.3.8 and fully fixed in 2.3.9

The vulnerability CVE-2024-7514 affects the WordPress Comments Import & Export plugin, representing a critical arbitrary file read flaw that undermines the security posture of WordPress installations. This vulnerability exists within the plugin's comments import functionality and specifically targets the validation mechanisms governing file paths during the import process. The flaw allows authenticated attackers who possess Author-level privileges or higher to exploit the system and access arbitrary files on the target server. The issue stems from inadequate input sanitization and validation of file paths, creating a direct pathway for unauthorized data access that can expose sensitive information including configuration files, database credentials, and other system artifacts. The vulnerability affects all plugin versions up to and including 2.3.7, with partial remediation introduced in version 2.3.8 and complete mitigation achieved in version 2.3.9.
The technical exploitation of this vulnerability leverages the plugin's import functionality to traverse the file system and read files that should remain protected from unauthorized access. Attackers can manipulate the import process to specify arbitrary file paths, bypassing normal access controls and permissions mechanisms. This flaw directly maps to CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. The vulnerability enables attackers to potentially read sensitive files such as wp-config.php, which contains database credentials, or other configuration files that could provide additional attack vectors or system information. The authentication requirement of Author-level access or higher represents a significant concern as it allows users who have contributed content to potentially escalate their privileges or extract sensitive data from the system.
The operational impact of CVE-2024-7514 extends beyond simple data exposure, as the ability to read arbitrary files can lead to complete system compromise. When attackers can access configuration files, they gain insights into database structures, application logic, and potential security weaknesses within the WordPress installation. This vulnerability can be particularly dangerous in multi-site installations or environments where multiple users have Author-level access, as it creates a persistent threat vector for data exfiltration. The vulnerability also aligns with ATT&CK technique T1213.002, which covers data from information repositories, and T1566.002, focusing on spearphishing attachments, as attackers may use this vulnerability to gather intelligence before launching more sophisticated attacks. Organizations using affected plugin versions face risks of regulatory compliance violations, data breaches, and potential system compromise that could result in extended downtime and financial losses.
Mitigation strategies for CVE-2024-7514 require immediate action to update the WordPress Comments Import & Export plugin to version 2.3.9 or later, which contains the complete fix for this vulnerability. System administrators should conduct thorough vulnerability assessments to identify all instances of the affected plugin across their WordPress installations and implement patch management procedures to ensure timely updates. Additional protective measures include implementing role-based access controls to limit Author-level privileges to only necessary users, monitoring import activities for suspicious file access patterns, and maintaining comprehensive backup procedures to quickly restore systems if exploitation occurs. The remediation process should also involve reviewing user access permissions and ensuring that only trusted individuals possess the necessary privileges to perform import operations. Organizations should consider implementing web application firewalls to detect and block suspicious file path traversal attempts and establish monitoring procedures to alert administrators of potential exploitation attempts. Regular security audits of WordPress plugins and themes remain essential to identify and address similar vulnerabilities before they can be exploited by malicious actors.
