CVE-2020-8641Public exploitNetwork attack vector

Authenticated local file inclusion via page_slug traversal

Published Feb 5, 2020 · Updated Aug 4, 2024

Local file inclusion in Lotus Core CMS 1.0.1 allows remote authenticated users to include PHP files via the page_slug parameter. index.php appends .php to page_slug, checks the resulting path with file_exists(), and includes it without sanitizing traversal sequences. A valid session is required; a crafted relative path with a null byte can select an existing local file for server-side inclusion.
