Descriptions

In vBulletin through 5.3.x, there is an unauthenticated deserialization vulnerability that leads to arbitrary file deletion and, under certain circumstances, code execution, because of unsafe usage of PHP's unserialize() in vB_Library_Template's cacheTemplates() function, which is a publicly exposed API. This is exploited with the templateidlist parameter to ajax/api/template/cacheTemplates.

En vBulletin hasta las versiones 5.3.x, hay una vulnerabilidad de deserialización no autenticada que conduce al borrado de archivos arbitrarios y, en ciertas circunstancias, la ejecución de código, debido al uso no seguro de unserialize() de PHP en la función cacheTemplates() de vB_Library_Template, que es una API expuesta públicamente expuesta. Esto se explota con el parámetro templateidlist en ajax/api/template/cacheTemplates.
