CVE-2024-13770
Published: 13 February 2025
Description
The Puzzles | WP Magazine / Review with Store WordPress Theme + RTL theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.2.4 via deserialization of untrusted input 'view_more_posts' AJAX action. 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. The developer opted to remove the software from the repository, so an update is not available and it is recommended to find a replacement software.
Security Summary
CVE-2024-13770 is a PHP Object Injection vulnerability (CWE-502) affecting the Puzzles | WP Magazine / Review with Store WordPress Theme + RTL theme for WordPress in all versions up to and including 4.2.4. The issue arises from deserialization of untrusted input in the 'view_more_posts' AJAX action, enabling unauthenticated attackers to inject arbitrary PHP objects. The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting high confidentiality, integrity, and availability impacts under specific conditions.
Unauthenticated attackers can exploit this vulnerability remotely over the network with high attack complexity by sending crafted requests to the affected AJAX endpoint. On its own, the theme lacks a known Property-Oriented Programming (POP) chain, resulting in no direct impact. However, if another plugin or theme on the target WordPress site provides a POP chain, exploitation could enable severe outcomes such as arbitrary file deletion, sensitive data retrieval, or remote code execution, depending on the chain's capabilities.
Advisories from Wordfence indicate that the developer has removed the theme from the repository, with no patch or update available. Security practitioners should recommend immediate replacement of the theme with a maintained alternative. Additional details are available in the Wordfence threat intelligence report and the original ThemeForest listing.
