Descriptions

The WordPress Gallery Plugin WordPress plugin before 3.39 is vulnerable to PHAR Deserialization due to a lack of input parameter validation in the `gallery_edit` function, allowing an attacker to access arbitrary resources on the server.

El complemento WordPress Gallery Plugin para WordPress anterior a 3.39 es vulnerable a PHAR Deserialization debido a la falta de validación de parámetros de entrada en la función `gallery_edit`, lo que permite a un atacante acceder a recursos arbitrarios en el servidor.

The WordPress Gallery Plugin – NextGEN Gallery plugin for WordPress is vulnerable to PHAR Deserialization in all versions up to, and including, 3.38 via deserialization of untrusted input in the gallery_edit function. This makes it possible for authenticated attackers, with administrative-level access and above, 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.
