  • No authentication required.
  • Targets `uploadify.php`.
  • Unauthenticated file upload.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability, an unauthenticated arbitrary file upload in a WordPress plugin, presents a significant risk as it allows for direct remote code execution. Attackers are highly motivated to exploit such flaws, especially in widely used platforms like WordPress, as successful exploitation can lead to complete server compromise. The ease of exploitation and the potential for widespread impact make it an attractive target.

  • Public exploit available.
  • Known to be exploited in the wild.
  • Affects internet-facing applications.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize immediate removal or disabling of the WP-Property plugin to mitigate unauthenticated file upload risk.
