CVE-2025-29709Public exploitNetwork attack vector

Remote code execution via unrestricted portfolio upload

Published Apr 16, 2025 · Updated Apr 17, 2025

Unrestricted file upload in SourceCodester Company Website CMS 1.0 allows remote attackers to execute code through the portfolio form. The createportfolio handler passes ufile to move_uploaded_file after only basename and random-prefix processing, without validating its extension or content. The published request includes a PHP session cookie, while CISA treats the endpoint as requiring no privileges; requesting the stored PHP file executes its payload.
