Unauthenticated file deletion via unchecked path traversal
Published Feb 10, 2022 · Updated Aug 3, 2024
Path traversal in Cuppa CMS 1.0 allows remote attackers to delete arbitrary server files through the file manager API. The deleteFile and deleteFolder actions pass the JSON path value to unlink and recursive directory removal without constraining it to the managed directory. No session is required, and deletion is limited to files writable by the PHP process, including application or access-control files.
