The ElementsKit Elementor addons plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.1.0 via the generate_navigation_markup function of the Onepage Scroll module. This vulnerability allows authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, enabling the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other 'safe' file types can be uploaded and included.
With a CVSS score of 8.8, this vulnerability is classified as high severity, indicating a significant risk to organizations. The potential for unauthorized access and data exposure is considerable, especially for installations that have not implemented proper access controls. The urgency for defenders is critical as the lack of a patch could lead to exploitation.
Currently, there are no known exploits or public proof-of-concept code available for this vulnerability. However, given the nature of Local File Inclusion vulnerabilities and the high CVSS score, organizations should be proactive in their response to mitigate risks.
Organizations should prioritize patching immediately. The risk associated with this vulnerability necessitates a thorough review of affected systems and potential remediation strategies.
Vulnerability Details
The vulnerability in the ElementsKit Elementor addons plugin stems from its ability to include files without proper validation. The affected function, generate_navigation_markup, does not adequately restrict file inclusions, allowing attackers to leverage this flaw.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, which indicates that the attack vector is network-based, requires low complexity, and low privileges. The impacts on confidentiality, integrity, and availability are all rated high, reinforcing the critical nature of this vulnerability.
The plugin is developed by wpmet, and all versions prior to the vendor's patch are affected. The vulnerability was published on May 2, 2024.
Technical Analysis
The root cause of the vulnerability lies in insufficient input validation in the generate_navigation_markup function. This oversight allows for Local File Inclusion, where attackers can include files from the server that they should not have access to. The attack vector is network-based, meaning that an attacker does not need physical access to the server.
The attack complexity is low, as it requires minimal effort to exploit, especially for authenticated users. Attackers require only contributor-level privileges to perform the attack, and no user interaction is necessary. The implications are severe, as successful exploitation could lead to high confidentiality, integrity, and availability impacts.
Risk & Impact Analysis
The real-world risk from this vulnerability includes potential unauthorized access to sensitive information, code execution on the server, and the potential for further exploitation through data exfiltration or service disruption. The blast radius could be significant, especially in environments where the plugin is widely used.
Organizations should assess the urgency of this vulnerability based on its high CVSS score and the availability of a patch. The risk to organizations includes the potential for data breaches and operational impacts if the vulnerability is exploited.

Affected Versions
All versions of the ElementsKit Elementor addons plugin prior to 3.1.1 are affected by this vulnerability. Users are advised to upgrade to the latest version immediately to mitigate risk.
Mitigation & Remediation
Organizations should implement the following mitigation strategies: apply the latest patch provided by wpmet for the ElementsKit Elementor addons plugin. If a patch cannot be applied immediately, organizations should consider restricting access to the plugin, disabling it, or implementing web application firewall rules to prevent exploitation.
For ongoing security, organizations may also consider engaging in penetration testing to identify similar vulnerabilities in their systems.
Detection Guidance
Organizations should monitor their systems for any unusual file access patterns or unexpected file inclusions. Log entries that indicate attempts to include unauthorized files could be a sign of exploitation attempts. Additionally, behavioral anomalies in user activity should be tracked to detect potential abuse.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in its potential to be exploited by attackers seeking to gain deeper access to WordPress installations. This incident underscores the necessity for organizations to continuously evaluate their plugins and ensure that they are regularly updated.
Security teams should take this opportunity to review their overall security posture and implement best practices for managing third-party components. Engaging in a comprehensive vulnerability management program can help mitigate the risks associated with vulnerabilities such as this one.
In conclusion, organizations must remain vigilant and prioritize patches for vulnerabilities that pose a high risk. This case illustrates the importance of proactive security measures to protect sensitive data and maintain the integrity of web applications.
