CVE-2024-39624 is a path traversal vulnerability identified in the ListingPro plugin developed by CridioStudio, affecting versions up to and including 2.9.4. The vulnerability arises from improper limitation of pathname inputs, allowing attackers to manipulate file paths to access restricted directories on the server. This flaw enables PHP Local File Inclusion (LFI), where an attacker can include and execute arbitrary files on the server, potentially leading to sensitive data disclosure or remote code execution if exploited in conjunction with other vulnerabilities. The issue stems from insufficient validation or sanitization of user-supplied input used in file path construction within the plugin’s codebase. ListingPro is a WordPress plugin widely used for directory and listing management, making it a common target in web environments. Although no public exploits have been reported yet, the nature of path traversal and LFI vulnerabilities makes them attractive targets for attackers due to their ability to bypass access controls and escalate privileges. The vulnerability was reserved in late June 2024 and published in August 2024, but no official patches or fixes have been linked yet. The absence of a CVSS score necessitates an independent severity assessment based on the vulnerability’s characteristics.

The primary impact of CVE-2024-39624 is unauthorized access to sensitive files on web servers running vulnerable versions of ListingPro. Attackers exploiting this vulnerability can read configuration files, source code, or other sensitive data, potentially leading to information disclosure that compromises confidentiality. In some cases, if combined with other vulnerabilities or misconfigurations, it could enable remote code execution, affecting integrity and availability. Organizations using ListingPro for directory listings or business listings risk exposure of customer data, internal credentials, or system files. This can lead to reputational damage, regulatory penalties, and further exploitation by threat actors. Since ListingPro is a WordPress plugin, the vulnerability affects a broad range of websites globally, including small businesses and enterprises relying on WordPress for their web presence. The ease of exploitation without authentication and the potential to escalate attacks make this a significant threat to affected organizations.

1. Monitor official CridioStudio and ListingPro channels for patches or updates addressing CVE-2024-39624 and apply them promptly once available. 2. Implement strict input validation and sanitization on all user-supplied data related to file paths within the plugin or custom code to prevent path traversal attempts. 3. Restrict file and directory permissions on the web server to limit the plugin’s access only to necessary files, minimizing the impact of potential exploitation. 4. Employ web application firewalls (WAFs) with rules designed to detect and block path traversal and LFI attack patterns targeting ListingPro endpoints. 5. Conduct regular security audits and code reviews of the plugin and associated customizations to identify and remediate insecure file handling. 6. Isolate critical web applications and sensitive data storage from publicly accessible directories to reduce exposure. 7. Educate site administrators on the risks of outdated plugins and the importance of timely updates and security best practices. 8. Consider temporary disabling or replacing ListingPro if immediate patching is not feasible, especially on high-risk or sensitive websites.
