Authenticated remote code execution via unrestricted upload
Published Jul 5, 2026 · Updated Jul 5, 2026
Unrestricted file upload in SourceCodester Onlne Examination & Learning Management System 1.0 allows remote authenticated users to execute code. The upload_files.php handler preserves an attacker-controlled filename extension and moves the upload into a web-served directory without type validation. Instructor or super_admin access is required, but default self-registration provides instructor access; an uploaded PHP webshell runs commands as the web-server account.
