CVE-2022-23375Public exploitNetwork attack vector

Authenticated code execution via unrestricted image upload

Published Feb 19, 2022 · Updated Aug 3, 2024

Unrestricted file upload in WikiDocs 0.1.18 allows remote authenticated users to execute code through the image upload form. The index.php upload flow trusts the POSTed filename extension and stores the file at a web-accessible path, allowing PHP content to run. An account with page-editing access is required; successful exploitation runs attacker-supplied PHP commands on the WikiDocs host.
