CVE-2024-0603Network attack vector

Unauthenticated data compromise via mylike deserialization

Published Jan 16, 2024 · Updated Jun 2, 2025

Deserialization in ZhiCms 4.0 and earlier allows remote attackers to process crafted data supplied through the mylike parameter. The request handler in app/plug/controller/giftcontroller.php sends attacker-controlled mylike data to an undisclosed deserialization operation; the exact function and usable object chain are not public. No authentication or user interaction is required, and published assessments establish data and service impact without identifying the resulting exploitation primitive.
