CVE-2025-41451Public exploitNetwork attack vector

Authenticated code execution via unsanitized email password

Published Aug 22, 2025 · Updated Aug 22, 2025

Command injection in Danfoss AK-SM 8xxA Series before 4.3.1 allows remote authenticated users to execute code through email settings. The SMTP configuration handler formats the email authentication password from item 0x1be1 directly into an OS shell command without sanitization. An administrative session and processing of the crafted email setting are required, after which the supplied shell directives execute on the controller.
