ClipBucket version 2.6 and earlier contains a critical vulnerability in the ofc_upload_image.php script located at /admin_area/charts/ofc-library/. This endpoint allows unauthenticated users to upload arbitrary files, including executable PHP scripts. Once uploaded, the attacker can access the file via a predictable path and trigger remote code execution.

→Monitor for unauthenticated HTTP POST requests targeting /admin_area/charts/ofc-library/ofc_upload_image.php, which is the vulnerable file upload endpoint requiring no authentication. ↗
→Alert on PHP file uploads (e.g., .php extension) delivered to the /admin_area/charts/ofc-library/ directory, followed by subsequent GET/POST requests to the same path — indicative of upload-then-execute RCE pattern. ↗
→Flag any web server process (e.g., Apache/nginx) spawning child processes (shells) originating from the /admin_area/charts/ofc-library/ directory, as this indicates successful RCE via the uploaded PHP webshell. ↗

·Exploitation confirmed on ClipBucket version 2.6 and earlier only; the Metasploit module was specifically tested on version 2.6 running on CentOS 5.9 32-bit — detection rules should be scoped accordingly. ↗
