Vulnerability Overview

The StopBadBots plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the stopbadbots_install_plugin() function in versions up to, and including, 7.23. 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 7.24, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
