Descriptions

The LearnPress WordPress plugin before 4.1.7.2 unserialises user input in a REST API endpoint available to unauthenticated users, which could lead to PHP Object Injection when a suitable gadget is present, leadint to remote code execution (RCE). To successfully exploit this vulnerability attackers must have knowledge of the site secrets, allowing them to generate a valid hash via the wp_hash() function.

El complemento LearnPress WordPress anterior a 4.1.7.2 deserializa la entrada del usuario en un punto final API REST disponible para usuarios no autenticados, lo que podría conducir a una Inyección de Objetos PHP cuando hay presente un dispositivo adecuado, lo que lleva a la ejecución remota de código (RCE). Para explotar con éxito esta vulnerabilidad, los atacantes deben tener conocimiento de los secretos del sitio, lo que les permitirá generar un hash válido a través de la función wp_hash().

The LearnPress plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 4.1.7.1 via deserialization of untrusted input in a REST API endpoint available to unauthenticated users. This allows 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.
