CVE-2020-21325Public exploitNetwork attack vector

Authenticated code execution via unfiltered cache content

Published Jun 20, 2023 · Updated Dec 9, 2024

Arbitrary PHP code execution in WUZHI CMS 4.1.0 allows remote authenticated users to run code through attachment settings. The attachment module's set action passes unfiltered setting data to set_cache, which writes non-array content directly into an executable PHP cache file. Administrative-panel access is required, and a later cache load executes the supplied PHP content with the web server's privileges.
