CVE-2022-38296Public exploitNetwork attack vector

Remote code execution via unrestricted file upload

Published Sep 12, 2022 · Updated Aug 3, 2024

Arbitrary file upload in Cuppa CMS v1.0 allows remote attackers to execute code via the File Manager upload workflow. The File Manager accepts a crafted upload, permits renaming it to a server-executable extension, and exposes the resulting path, enabling a PHP web shell. A reachable installation therefore permits server compromise with confidentiality, integrity, and availability impact.
