Descriptions

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.

El complemento Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag &amp; Drop WP Form Builder para WordPress es vulnerable a la inyección de objetos PHP en todas las versiones hasta la 5.1.15 incluida a través de la deserialización de entradas que no son de confianza en la función extractDynamicValues. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador y superior, inyecten un objeto PHP. Si hay una cadena POP presente a través de un complemento o tema adicional instalado en el sistema de destino, podría permitir al atacante eliminar archivos arbitrarios, recuperar datos confidenciales o ejecutar código. La explotación exitosa requiere que el atacante tenga los permisos "Ver formulario" y "Administrar formulario", que deben ser establecidos explícitamente por un administrador. Sin embargo, este requisito se puede eludir cuando esta vulnerabilidad se encadena con CVE-2024-2771.
