CVE-2013-10040: ClipBucket <= 2.6 ofc_upload_image.php Arbitrary File Upload RCE

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.

Security readout for executives and security teams

Plain-English summary

ClipBucket 2.6 and earlier reportedly lets unauthenticated outsiders upload files that can execute server-side code. A successful attack could give control of the web application and host data. This is critical for any internet-facing ClipBucket deployment, but the supplied CVE data does not show CISA KEV listing or confirmed active exploitation.

Executive priority

Treat as urgent for any confirmed ClipBucket deployment. The vulnerability is remotely reachable, unauthenticated, and can lead to full application compromise. Prioritize asset discovery, containment of public exposure, and vendor-supported remediation before routine hardening work.

Technical view

The issue is CWE-434 in ofc_upload_image.php under the admin chart library. The bundle describes unauthenticated arbitrary upload of executable PHP, leading to remote code execution. CVSS v4.0 is 10.0 with network access, low complexity, no privileges, and no user interaction.

Likely exposure

Highest exposure is public ClipBucket 2.6 or earlier, especially legacy video-sharing sites still reachable from the internet. The supplied affected record is inconsistent, listing version "0" while the description says 2.6 and earlier, so asset confirmation matters.

Exploitation context

Public exploit references exist from Rapid7 Metasploit and Packet Storm, so the technique is publicly documented. However, the source bundle marks KEV as false and provides no cited evidence of active exploitation in the wild.

Researcher notes

Evidence supports critical severity and public exploit availability, but not confirmed active exploitation. The affected-version metadata conflicts with the narrative description, so validation should rely on local version evidence and vendor or CVE updates rather than assumptions.

Mitigation direction

  • Identify and prioritize all ClipBucket deployments, especially internet-facing legacy instances.
  • Check official ClipBucket and CVE guidance for supported fixed versions or vendor mitigations.
  • Restrict public access to administrative and upload-related paths where business permits.
  • Remove unsupported ClipBucket instances or isolate them behind strong access controls.
  • Review uploaded files and webroot contents for unexpected executable files.

Validation and detection

  • Confirm product name, installed version, and exposure path for every ClipBucket instance.
  • Review web server logs for unexpected upload activity and suspicious PHP file access.
  • Inspect application upload directories and webroot for unauthorized executable files.
  • Verify administrative and upload endpoints are not anonymously reachable from the internet.
  • Track CVE, VulnCheck, and vendor pages for updated affected-version and remediation details.
