Five Star Restaurant Menu and Food Ordering <= 2.4.10 - Unauthenticated PHP Object Injection

Deserialization of Untrusted Data
CVE CVE-2023-5340
CVSS Critical (9.8)
Publicly Published October 27, 2023
Last Updated January 22, 2024
Researcher Krzysztof Zając
Description

The Five Star Restaurant Menu and Food Ordering plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.4.10 via deserialization of untrusted input from the 'options' parameter supplied via the 'fdm_update_cart_item' AJAX action. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the 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.
