CVE-2024-3346Public exploitNetwork attack vector

Authenticated command execution via unsanitized mail_file_path

Published Apr 5, 2024 · Updated Aug 1, 2024

OS command injection in Byzoro Smart S80 Management Platform 20240328 and earlier allows remote authenticated users to run commands via mail_file_path. The /log/webmailattach.php handler passes the attacker-controlled mail_file_path value directly to exec without neutralizing shell metacharacters. A valid PHP session is required; successful exploitation runs commands with the web service account's privileges and permits server-file manipulation.
