CVE-2023-33440Public exploitNetwork attack vector

Authenticated code execution via unrestricted image upload

Published May 26, 2023 · Updated Jan 14, 2025

Arbitrary code execution in SourceCodester Faculty Evaluation System 1.0 allows remote authenticated users to execute PHP via image upload. The save_user handler accepts a PHP file in the img field and stores it under the web-accessible /eval/assets/uploads directory without restricting executable content. A high-privilege web session is required; retrieving the uploaded file executes attacker-controlled code in the web server context.
