CVE-2013-10040Public exploitNetwork attack vector

Unauthenticated code execution via arbitrary PHP upload

Published Jul 31, 2025 · Updated May 15, 2026

Unrestricted file upload in ClipBucket 2.6 and earlier allows remote attackers to execute arbitrary PHP through an unauthenticated endpoint. The ofc_upload_image.php script writes a caller-named request body into admin_area/charts/tmp-upload-images without restricting executable extensions. No account is required, and requesting the predictable uploaded path executes the file with the web server's privileges.
