CVE-2024-4157 Information

Description

The Contact Form Plugin by Fluent Forms for Quiz Survey and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 5.1.15 via deserialization of untrusted input in the extractDynamicValues function. This makes it possible for authenticated attackers with contributor-level access and above to inject a PHP Object. 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. Successful exploitation requires the attacker to have \View Form\ and \Manage Form\ permissions which must be explicitly set by an administrator. However this requirement can be bypassed when this vulnerability is chained with CVE-2024-2771.
