Security News > 2023 > January > 75k WordPress sites impacted by critical online course plugin flaws
The WordPress online course plugin 'LearnPress' was vulnerable to multiple critical-severity flaws, including pre-auth SQL injection and local file inclusion.
LearnPress is a learning management system plugin that allows WordPress websites to easily create and sell online courses, lessons, and quizzes, providing visitors with a friendly interface while requiring no coding knowledge from the website developer.
The first vulnerability discovered by PatchStack is CVE-2022-47615, an unauthenticated local file inclusion flaw that allows attackers to display the contents of local files stored on the web server.
The second critical flaw is CVE-2022-45808, an unauthenticated SQL injection potentially leading to sensitive information disclosure, data modification, and arbitrary code execution.
The third flaw impacting older LearnPress versions is CVE-2022-45820, an authenticated SQL injection flaw in two shortcodes of the plugin failing to properly validate and sanitize the input of the "$args" variable.
Website owners relying on LearnPress are advised to either upgrade to version 4.2.0 or disable the plugin until they can apply the available security update.
