Summary
The Redirection for Contact Form 7 plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.2.4 via deserialization of untrusted input in the delete_associated_files function. This makes it possible for unauthenticated attackers to inject a PHP Object. This vulnerability may be exploited by unauthenticated attackers when a form is present on the site with a file upload action, and doesn't affect sites with PHP version > 8. This vulnerability also requires the 'Redirection For Contact Form 7 Extension - Create Post' extension to be installed and activated in order to be exploited. 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. We confirmed there is a usable gadget in Contact Form 7 plugin that makes arbitrary file deletion possible when installed with this plugin. Given Contact Form 7 is a requirement of this plugin, it is likely that any site with this plugin and the 'Redirection For Contact Form 7 Extension - Create Post' extension enabled is vulnerable to arbitrary file deletion.

"value": "El complemento Redirection for Contact Form 7 para WordPress es vulnerable a la inyecci\u00f3n de objetos PHP en todas las versiones hasta la 3.2.4 incluida, mediante la deserializaci\u00f3n de entradas no confiables en la funci\u00f3n delete_associated_files. Esto permite a atacantes no autenticados inyectar un objeto PHP. Esta vulnerabilidad puede ser explotada por atacantes no autenticados cuando hay un formulario en el sitio con una acci\u00f3n de carga de archivos, y no afecta a sitios con PHP versi\u00f3n \u0026gt; 8. Esta vulnerabilidad tambi\u00e9n requiere la instalaci\u00f3n y activaci\u00f3n de la extensi\u00f3n \"Redirection For Contact Form 7 Extension - Create Post\" para ser explotada. No se conoce ninguna cadena POP presente en el software vulnerable, por lo que esta vulnerabilidad no tiene impacto a menos que se instale en el sitio otro complemento o tema que contenga una cadena POP. Si una cadena POP est\u00e1 presente a trav\u00e9s de un complemento o tema adicional instalado en el sistema objetivo, puede permitir al atacante realizar acciones como eliminar archivos arbitrarios, recuperar datos confidenciales o ejecutar c\u00f3digo, dependiendo de la cadena POP presente. Confirmamos que existe un gadget \u00fatil en el complemento Contact Form 7 que permite la eliminaci\u00f3n arbitraria de archivos al instalarlo. Dado que Contact Form 7 es un requisito de este complemento, es probable que cualquier sitio que lo tenga habilitado y la extensi\u00f3n \"Redirecci\u00f3n para la extensi\u00f3n Contact Form 7 - Crear publicaci\u00f3n\" sea vulnerable a la eliminaci\u00f3n arbitraria de archivos."
