Descriptions

The Better Search Replace plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.4.4 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable 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.

El complemento Better Search Replace para WordPress es vulnerable a la inyección de objetos PHP en todas las versiones hasta la 1.4.4 incluida, a través de la deserialización de entradas que no son de confianza. Esto hace posible que atacantes no autenticados inyecten un objeto PHP. No hay ninguna cadena POP presente en el complemento vulnerable. 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.
