Vulnerability Overview

The Anti Hacker plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the antihacker_install_plugin() function in versions up to, and including, 4.19. This makes it possible for authenticated attackers with minimal permission, such as a subscriber, to install arbitrary plugins on the vulnerable site. This could be used to install additional vulnerable plugins that could aid in further compromise of the site.

Technical Analysis

REMEDIATION: Update to version 4.20, or a newer patched version --- IDENTIFIER: CWE-284 (Improper Access Control) The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
