CVE-2024-9611: Increase upload file size plugin allows attackers to inject malicious scripts

CVE-2024-9611 · published 2 years ago

Summary

The Increase upload file size & Maximum Execution Time limit plugin for WordPress has a security flaw that allows hackers to inject malicious code into websites. This could happen if a user clicks on a link sent by the hacker. To protect your site, update the plugin to the latest version.

Original advisory text

The Increase upload file size & Maximum Execution Time limit plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.0. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
