CVE-2011-10041: Uploadify <= 1.0 Unauthenticated Arbitrary File Upload

Uploadify WordPress plugin versions up to and including 1.0 contain an arbitrary file upload vulnerability in process_upload.php due to missing file type validation. An unauthenticated remote attacker can upload arbitrary files to the affected WordPress site, which may allow remote code execution by uploading executable content to a web-accessible location.

Security readout for executives and security teams

Plain-English summary

CVE-2011-10041 affects the legacy Uploadify WordPress plugin through version 1.0. The upload handler lacks file type validation, allowing unauthenticated remote users to upload arbitrary files. If executable content lands in a web-accessible path, the site may be taken over. Treat exposed instances as urgent, especially on internet-facing WordPress sites.

Executive priority

Prioritize this as critical for any internet-facing WordPress site using the affected plugin. The business risk is full site compromise, data exposure, service disruption, and potential downstream abuse from a trusted web domain.

Technical view

The vulnerability is CWE-434 in process_upload.php. Sources describe unauthenticated arbitrary file upload caused by missing file type validation. The CVSS 4.0 score is 9.3, with network access, low complexity, no privileges, and no user interaction. Impact is high for confidentiality, integrity, and availability on the vulnerable system.

Likely exposure

Likely exposure is limited to WordPress sites that still have Uploadify plugin version 1.0 or earlier installed and reachable. Public internet exposure materially increases risk. The provided affected-product metadata is sparse, so confirm plugin presence directly rather than relying only on asset inventory names.

Exploitation context

A public exploit reference is listed by Packet Storm, but the source bundle does not state active exploitation. The CVE is not marked as CISA KEV. Do not assume current exploitation without additional evidence from authoritative threat intelligence or incident telemetry.

Researcher notes

Evidence supports unauthenticated arbitrary file upload and possible remote code execution when uploaded executable content is web-accessible. Public exploit material exists, but active exploitation is not established in the bundle. Affected metadata appears incomplete, so validate against plugin files, version, and route exposure.

Mitigation direction

  • Identify and disable or remove Uploadify version 1.0 or earlier.
  • Check vendor or plugin repository guidance for any maintained replacement or fixed version.
  • Restrict public access to process_upload.php if the plugin cannot be removed immediately.
  • Review uploaded files and web-accessible directories for unexpected executable content.
  • Restore affected sites from known-good backups if compromise is confirmed.

Validation and detection

  • Inventory WordPress plugins and confirm whether Uploadify is installed.
  • Verify the installed Uploadify version is newer than 1.0 or absent.
  • Check whether process_upload.php is reachable without authentication.
  • Review web logs for unauthenticated upload attempts to the plugin path.
  • Inspect upload directories for unexpected scripts or newly created executable files.
