CVE-2023-27842Public exploitNetwork attack vector

Authenticated arbitrary code execution

Published Mar 21, 2023 · Updated Feb 26, 2025

Insecure permissions in eXtplorer 2.1.15 allow remote authenticated users to execute arbitrary code through index.php. Public records identify index.php as the affected component but do not disclose which permission check or operation mishandles attacker-controlled input. A valid low-privilege account is required, and successful exploitation grants code execution in the file manager's server context.
