CVE-2024-3431Public exploitNetwork attack vector

Authenticated code execution via channel_id deserialization

Published Apr 7, 2024 · Updated Aug 20, 2024

Deserialization in the EyouCMS 1.6.5 Backend allows remote authenticated users to execute code through a crafted channel_id value. The channel_edit action processes attacker-controlled channel_id data through deserialization, while the public disclosure omits the exact function and object chain. Administrative Backend access is required, and successful exploitation runs code within the web application process.
