CVE-2020-24914Public exploitNetwork attack vector

Unauthenticated code execution via profile data deserialization

Published Mar 4, 2021 · Updated Jul 9, 2026

PHP object injection in QCubed Framework 3.1.1 and earlier allows remote attackers to execute code through a crafted POST request. profile.php base64-decodes strProfileData and passes the attacker-controlled bytes directly to PHP unserialize(). The attack requires network access to profile.php but no authentication or user interaction, and successful exploitation runs code in the web application's process context.
