CVE-2024-54376 is a Local File Inclusion (LFI) vulnerability found in the Spider Themes EazyDocs WordPress plugin, specifically in versions up to 2.8.0. The vulnerability arises from improper validation and control of filenames used in PHP include or require statements. This flaw allows an attacker to manipulate the filename parameter to include arbitrary files from the server's filesystem. By exploiting this, an attacker can read sensitive files such as configuration files, password files, or other critical data stored on the server. In some cases, LFI can be leveraged to execute arbitrary code if the attacker can upload malicious files or if log files can be included. The vulnerability does not require authentication, making it accessible to unauthenticated remote attackers. Although no public exploits have been reported yet, the nature of the vulnerability makes it a significant risk. The plugin is widely used in WordPress environments for documentation purposes, increasing the attack surface. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability is classified as a PHP Remote File Inclusion type but technically is a Local File Inclusion due to the improper control of include paths. The issue was published on December 16, 2024, and no official patches or mitigation links are currently provided, indicating the need for immediate attention from users of the plugin.

The primary impact of CVE-2024-54376 is unauthorized disclosure of sensitive information through Local File Inclusion. Attackers can read server files that may contain credentials, configuration details, or other sensitive data, leading to further compromise. In some scenarios, LFI can be escalated to remote code execution, especially if combined with other vulnerabilities or misconfigurations. This can result in full server compromise, data theft, defacement, or use of the server as a pivot point for lateral movement. Organizations relying on EazyDocs for documentation on WordPress sites face risks of data leakage and service disruption. The vulnerability affects the integrity and confidentiality of the affected systems and can impact availability if exploited to disrupt services. Given the widespread use of WordPress and the popularity of documentation plugins, the scope of affected systems is significant. The lack of authentication requirement and ease of exploitation increase the threat level. This vulnerability could be leveraged by attackers ranging from opportunistic hackers to advanced persistent threat groups targeting organizations with public-facing WordPress sites.

1. Immediately monitor for updates from Spider Themes and apply any patches or updates addressing this vulnerability as soon as they become available. 2. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block suspicious requests attempting to exploit file inclusion, such as those containing directory traversal sequences or unusual filename parameters. 3. Restrict PHP include paths in the server configuration to prevent inclusion of arbitrary files outside intended directories. 4. Harden the WordPress environment by disabling unnecessary plugins and limiting file permissions to reduce the attack surface. 5. Conduct regular security audits and scanning of WordPress sites to detect vulnerable plugin versions. 6. Employ intrusion detection systems to monitor for anomalous file access patterns. 7. Educate site administrators on the risks of using outdated plugins and the importance of timely updates. 8. Consider isolating critical WordPress instances in segmented network zones to limit potential lateral movement if compromised. 9. Review server logs for any signs of exploitation attempts and respond promptly to incidents. 10. If feasible, temporarily disable or replace the EazyDocs plugin until a secure version is released.
