CVE-2025-41735Network attack vector

Remote code execution via unchecked file upload

Published Nov 18, 2025 · Updated Nov 18, 2025

Unrestricted file upload in METZ CONNECT EWIO2 firmware before 2.2.0 allows remote authenticated users to execute arbitrary code. An unspecified upload handler omits a file check and accepts attacker-controlled files for placement at arbitrary filesystem locations. Low-privileged device access is required; successful uploads can compromise device confidentiality, integrity, and availability.
