Description
The AP Background plugin for WordPress is vulnerable to arbitrary file uploads due to missing authorization and insufficient file validation within the advParallaxBackAdminSaveSlider() handler in versions 3.8.1 to 3.8.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Executive Summary

The AP Background plugin for WordPress has a vulnerability in versions 3.8.1 to 3.8.2 that allows authenticated users with Subscriber-level access or higher to upload arbitrary files to the server. This happens because the advParallaxBackAdminSaveSlider() handler lacks proper authorization checks and sufficient file validation, potentially enabling remote code execution.

Impact Analysis

This vulnerability can allow attackers with low-level access to upload malicious files to the server, which may lead to remote code execution. This can compromise the website, allowing attackers to execute arbitrary commands, steal data, or take control of the server.
