CVE-2023-4414Public exploitNetwork attack vector

Authenticated command injection via file parameter

Published Aug 18, 2023 · Updated Nov 21, 2024

Command injection in Smart S85F Management Platform 20230807 allows remote authenticated users to execute commands through the decodmail.php file parameter. The /log/decodmail.php endpoint base64-decodes the file argument and passes crafted backtick content into a shell command, enabling execution. A valid web session is required; successful requests run attacker-selected commands with the platform service account's privileges.
