CVE-2026-5546 Details
Description
A flaw has been found in Campcodes Complete Online Learning Management System 1.0. This impacts the function add_lesson of the file /application/models/Crud_model.php. This manipulation causes unrestricted upload. It is possible to initiate the attack remotely. The exploit has been published and may be used.
A critical vulnerability allowing unrestricted file uploads has been identified in Campcodes Complete Online Learning Management System version 1.0. The issue arises in the 'add_lesson' function within '/application/models/Crud_model.php', where the application fails to properly validate file extensions during the lesson attachment upload process. Instead of enforcing a secure whitelist, the system renames uploaded files using an MD5 hash while blindly appending the original, user-supplied extension, such as '.php'. This vulnerability can be exploited remotely, and the uploaded files' paths are disclosed in the HTML source code, allowing for easy execution of malicious payloads.
